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. In reality, the total ATP yield is usually less, ranging from one to 34 ATP molecules, depending on whether the cell is using aerobic respiration or anaerobic respiration; in eukaryotic cells, some energy is expended to transport intermediates from the cytoplasm into the mitochondria, affecting ATP yield. Glucose is broken down into 2 molecules of pyruvic acid, which becomes a reactant in the Krebs cycle. Microbes using anaerobic respiration commonly have an intact Krebs cycle, so these organisms can access the energy of the NADH and FADH2 molecules formed.

Pages 12 to 22 are not shown in this preview. The tendency for movement in this way is much like water accumulated on one side of a dam, moving through the dam when opened.

9.2 The Process Of Cellular Respiration Answer Key Solution

2 The Process of Cellular Respiration. With each rotation, the ATP synthase attaches a phosphate to ADP to produce ATP. In prokaryotic cells, H+ is pumped to the outside of the cytoplasmic membrane (called the periplasmic space in gram-negative and gram-positive bacteria), and in eukaryotic cells, they are pumped from the mitochondrial matrix across the inner mitochondrial membrane into the intermembrane space. In aerobic respiration, the final electron acceptor (i. 9.2 the process of cellular respiration answer key 2021. e., the one having the most positive redox potential) at the end of the ETS is an oxygen molecule (O2) that becomes reduced to water (H2O) by the final ETS carrier. Cellular Respiration: The Citric Acid Cycle (or Krebs Cycle). All in all, the breakdown of a single molecule of glucose yields 36 molecules of ATP. Complex carbohydrates are broken down into simple sugars like glucose. Citric Acid Production Once pyruvic acid is in the mitochondrial matrix, NAD+ accepts 2 high-energy electrons to form NADH. What are the functions of the proton motive force?

9.2 The Process Of Cellular Respiration Answer Key 2021

At this point, try not to worry about the names of compounds or the details of the processes shown. Now that we have studied each stage of cellular respiration in detail, let's take another look at the equation that summarizes cellular respiration and see how various processes relate to it: 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 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.

9.2 The Process Of Cellular Respiration Answer Key Questions

The NADH carries high-energy electrons to the electron transport chain, where they are used to produce ATP. 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. Equation for Cellular Respiration. I tried my best to visually layout the metabolic pathways of Cellular Respiration for my AP Biology students. 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.

9.2 The Process Of Cellular Respiration Answer Key Unit

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. Most ATP, however, is generated during a separate process called oxidative phosphorylation, which occurs during cellular respiration. ATP is a source of usable energy for cells and is the key energy molecule for all biological organisms. One possible alternative to aerobic respiration is anaerobic respiration, using an inorganic molecule other than oxygen as a final electron acceptor. Energy Totals In the presence of oxygen, the complete breakdown of glucose through cellular respiration could produce 38 ATP molecules. Great for middle school or introductory high school courses. Weakness is your body's way of telling you that your energy supplies are low. Glycolysis is an anaerobic process, meaning it occurs without oxygen. When you are hungry, how do you feel? 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 number of ATP molecules generated from the catabolism of glucose varies. 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. Glycolysis does not require oxygen, so it can quickly supply energy to cells when oxygen is unavailable.

9.2 The Process Of Cellular Respiration Answer Key Answer

Two molecules of CO2 are released. This represents about 36 percent of the total energy of glucose. ATP Production H+ ions pass back across the mitochondrial membrane through the ATP synthase, causing the ATP synthase molecule to spin. So each molecule of glucose results in two complete "turns" of the Krebs cycle. Energy Totals The cell can generate ATP from just about any source, even though we've modeled it using only glucose.

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. We have just discussed two pathways in glucose catabolism—glycolysis and the Krebs cycle—that generate ATP by substrate-level phosphorylation. Cellular Respiration: Electron Transport Chain. 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. Cellular Respiration Overview. 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.

The remaining 2 carbon atoms react to form acetyl-CoA. Describe the function and location of ATP synthase in a prokaryotic versus eukaryotic cell. This 22 slide PowerPoint presentation covers 8 questions on the topic of cellular respiration. These ATP molecules come from glycolysis, the Krebs cycle, and the electron transport chain. Therefore, for each glucose molecule, 6 CO2 molecules, 2 ATP molecules, 8 NADH molecules, and 2 FADH2 molecules are produced in the Kreb's cycle.. Electron Transport NADH and FADH2 pass their high-energy electrons to electron carrier proteins in the electron transport chain. Overall, 2 molecules of ATP are produced. There are many types of anaerobic respiration found in bacteria and archaea. Compare and contrast the differences between substrate-level and oxidative phosphorylation.

Also, 2 molecules of NADH are made. For example, the gram-negative opportunist Pseudomonas aeruginosa and the gram-negative cholera-causing Vibrio cholerae use cytochrome c oxidase, which can be detected by the oxidase test, whereas other gram-negative Enterobacteriaceae, like E. coli, are negative for this test because they produce different cytochrome oxidase types. 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. 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.

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. These carriers can pass electrons along in the ETS because of their redox potential. 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. Under aerobic conditions (i. e., oxygen is present), the pyruvate and NADH molecules made during glycolysis move from the cytoplasm into the matrix of the mitochondria. I also think that even if you don't use fill-in-the. Lipids and proteins can be broken down into molecules that enter the Krebs cycle or glycolysis at one of several places.

The cell lacks a sufficient amount of oxygen to carry out aerobic respiration. Therefore, electrons move from electron carriers with more negative redox potential to those with more positive redox potential. The remaining 64 percent is released as heat. 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). 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.
