Therefore, electrons move from electron carriers with more negative redox potential to those with more positive redox potential. Overall, the theoretical maximum yield of ATP made during the complete aerobic respiration of glucose is 38 molecules, with four being made by substrate-level phosphorylation and 34 being made by oxidative phosphorylation (Figure 8. The electron transport chain (ETC) is the final stage of cellular respiration. 2 ATP are usually required to bring the pyruvic acid into the matrix. What are the functions of the proton motive force? Explain the relationship between chemiosmosis and proton motive force.
9.2 The Process Of Cellular Respiration Answer Key 2021
Citric Acid Production Once pyruvic acid is in the mitochondrial matrix, NAD+ accepts 2 high-energy electrons to form NADH. In each transfer of an electron through the ETS, the electron loses energy, but with some transfers, the energy is stored as potential energy by using it to pump hydrogen ions (H+) across a membrane. I made these as a resource for my students to use while studying and do not use them as guided notes during my instruction, however, I did include a fill-in-the-blanks version for any teacher who'd prefer that style. ATP is a source of usable energy for cells and is the key energy molecule for all biological organisms. The tendency for movement in this way is much like water accumulated on one side of a dam, moving through the dam when opened. Citric Acid Production Pyruvic acid from glycolysis enters the matrix, the innermost compartment of the mitochondrion. Pages 12 to 22 are not shown in this preview. At this point, try not to worry about the names of compounds or the details of the processes shown. Cellular Respiration: Glycolysis. Many aerobically respiring bacteria, including E. coli, switch to using nitrate as a final electron acceptor and producing nitrite when oxygen levels have been depleted. There pyruvate feeds into the next stage of respiration, which is called the citric acid cycle (or Krebs cycle). So each molecule of glucose results in two complete "turns" of the Krebs cycle.
The potential energy of this electrochemical gradient generated by the ETS causes the H+ to diffuse across a membrane (the plasma membrane in prokaryotic cells and the inner membrane in mitochondria in eukaryotic cells). Glucose is broken down into 2 molecules of pyruvic acid, which becomes a reactant in the Krebs cycle. Equation for Cellular Respiration. The answer is cellular respiration. There is an uneven distribution of H+ across the membrane that establishes an electrochemical gradient because H+ ions are positively charged (electrical) and there is a higher concentration (chemical) on one side of the membrane. In aerobic respiration in mitochondria, the passage of electrons from one molecule of NADH generates enough proton motive force to make three ATP molecules by oxidative phosphorylation, whereas the passage of electrons from one molecule of FADH2 generates enough proton motive force to make only two ATP molecules. Glycolysis does not require oxygen, so it can quickly supply energy to cells when oxygen is unavailable. The energy of the electrons is harvested to generate an electrochemical gradient across the membrane, which is used to make ATP by oxidative phosphorylation. The Krebs cycle is also known as the citric acid cycle because citric acid is the first compound formed in this series of reactions. ATP synthase (like a combination of the intake and generator of a hydroelectric dam) is a complex protein that acts as a tiny generator, turning by the force of the H+ diffusing through the enzyme, down their electrochemical gradient from where there are many mutually repelling H+ to where there are fewer H+. The remaining 2 carbon atoms react to form acetyl-CoA.
9.2 The Process Of Cellular Respiration Answer Key Quiz
This flow of hydrogen ions across the membrane, called chemiosmosis, must occur through a channel in the membrane via a membrane-bound enzyme complex called ATP synthase (Figure 8. All in all, the breakdown of a single molecule of glucose yields 36 molecules of ATP. Main points include: respiraton, what happens during respiration, mitochondria, the two stages of respiration, the respiration equation, comparing photosynthesis with respiration, fermentation, and the two types of fermentation. One possible alternative to aerobic respiration is anaerobic respiration, using an inorganic molecule other than oxygen as a final electron acceptor. Cellular Respiration Summary. Describe the function and location of ATP synthase in a prokaryotic versus eukaryotic cell. Cellular respiration is often expressed as a chemical equation: This equation shows that during cellular respiration, one glucose molecule is gradually broken down into carbon dioxide and water. However, anaerobic respirers use altered ETS carriers encoded by their genomes, including distinct complexes for electron transfer to their final electron acceptors.
Beyond the use of the PMF to make ATP, as discussed in this chapter, the PMF can also be used to drive other energetically unfavorable processes, including nutrient transport and flagella rotation for motility. The cell lacks a sufficient amount of oxygen to carry out aerobic respiration. These carriers can pass electrons along in the ETS because of their redox potential. Also, 2 molecules of NADH are made. We have just discussed two pathways in glucose catabolism—glycolysis and the Krebs cycle—that generate ATP by substrate-level phosphorylation. Cellular Respiration: The Citric Acid Cycle (or Krebs Cycle). Energy Extraction Each molecule of glucose results in 2 molecules of pyruvic acid, which enter the Krebs cycle. Glycolysis Glycolysis - first stage of cellular respiration.
9.2 The Process Of Cellular Respiration Answer Key Of Life
A large amount of ATP is generated during this stage — 32 ATP molecules to be exact! Most ATP, however, is generated during a separate process called oxidative phosphorylation, which occurs during cellular respiration. I tried my best to visually layout the metabolic pathways of Cellular Respiration for my AP Biology students. It's actually quite amazing.
The number of ATP molecules generated from the catabolism of glucose varies. Directions: Watch The Citric Acid Cycle: An Overview to see how pyruvate is broken down during the citric acid cycle. I also think that even if you don't use fill-in-the. The electron transport system (ETS) is the last component involved in the process of cellular respiration; it comprises a series of membrane-associated protein complexes and associated mobile accessory electron carriers (Figure 8. Overall, 2 molecules of ATP are produced. Compare and contrast aerobic and anaerobic respiration. The four major classes of electron carriers involved in both eukaryotic and prokaryotic electron transport systems are the cytochromes, flavoproteins, iron-sulfur proteins, and the quinones. Cellular respiration begins when electrons are transferred from NADH and FADH2—made in glycolysis, the transition reaction, and the Krebs cycle—through a series of chemical reactions to a final inorganic electron acceptor (either oxygen in aerobic respiration or non-oxygen inorganic molecules in anaerobic respiration). Two molecules of CO2 are released. Can be used with Cornell notes. Thus, the 10 NADH molecules made per glucose during glycolysis, the transition reaction, and the Krebs cycle carry enough energy to make 30 ATP molecules, whereas the two FADH2 molecules made per glucose during these processes provide enough energy to make four ATP molecules.
9.2 The Process Of Cellular Respiration Answer Key Question
Energy Extraction Citric acid is broken down into a 5-carbon compound and then a 4-carbon compound. Electron transport is a series of chemical reactions that resembles a bucket brigade in that electrons from NADH and FADH2 are passed rapidly from one ETS electron carrier to the next. This 22 slide PowerPoint presentation covers 8 questions on the topic of cellular respiration. Chemiosmosis, Proton Motive Force, and Oxidative Phosphorylation.
The turning of the parts of this molecular machine regenerates ATP from ADP and inorganic phosphate (Pi) by oxidative phosphorylation, a second mechanism for making ATP that harvests the potential energy stored within an electrochemical gradient. These electron transfers take place on the inner part of the cell membrane of prokaryotic cells or in specialized protein complexes in the inner membrane of the mitochondria of eukaryotic cells. The NADH carries high-energy electrons to the electron transport chain, where they are used to produce ATP. Watch for a general overview.
9.2 The Process Of Cellular Respiration Answer Key Worksheet
Carbons are broken down and released as carbon dioxide while ATP is made and electrons are passed to electron carriers, NADH and FADH2. There are many types of anaerobic respiration found in bacteria and archaea. Microbes using anaerobic respiration commonly have an intact Krebs cycle, so these organisms can access the energy of the NADH and FADH2 molecules formed. Everything you want to read. Because the ions involved are H+, a pH gradient is also established, with the side of the membrane having the higher concentration of H+ being more acidic. Great for middle school or introductory high school courses. By the end of this section, you will be able to: - Compare and contrast the electron transport system location and function in a prokaryotic cell and a eukaryotic cell. Lipids and proteins can be broken down into molecules that enter the Krebs cycle or glycolysis at one of several places. The cell lacks genes encoding enzymes to minimize the severely damaging effects of dangerous oxygen radicals produced during aerobic respiration, such as hydrogen peroxide (H2O2) or superoxide. One molecule of CO2 is also produced. If you are like most people, you feel sluggish, a little dizzy, and weak.
For example, the number of hydrogen ions that the electron transport system complexes can pump through the membrane varies between different species of organisms. With each rotation, the ATP synthase attaches a phosphate to ADP to produce ATP. You're Reading a Free Preview. Compare and contrast the differences between substrate-level and oxidative phosphorylation. There are many circumstances under which aerobic respiration is not possible, including any one or more of the following: - The cell lacks genes encoding an appropriate cytochrome oxidase for transferring electrons to oxygen at the end of the electron transport system. ATP Production H+ ions pass back across the mitochondrial membrane through the ATP synthase, causing the ATP synthase molecule to spin.
These nutrients enter your cells and are converted into adenosine triphosphate ( ATP). This electrochemical gradient formed by the accumulation of H+ (also known as a proton) on one side of the membrane compared with the other is referred to as the proton motive force (PMF). Learning Objectives. Reward Your Curiosity.
Smaller electrochemical gradients are generated from these electron transfer systems, so less ATP is formed through anaerobic respiration. This electron carrier, cytochrome oxidase, differs between bacterial types and can be used to differentiate closely related bacteria for diagnoses. The Advantages of Glycolysis Glycolysis produces ATP very fast, which is an advantage when the energy demands of the cell suddenly increase. Glycolysis takes place in the cytoplasm of the cell. Electron Transport Energy generated by the electron transport chain is used to move H+ ions against a concentration gradient across the inner mitochondrial membrane and into the intermembrane space.
