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. Cellular Respiration: Electron Transport Chain. When you eat, your body digests the food into smaller chemical compounds like sugars (glucose), fats, and proteins. The electron transport chain (ETC) is the final stage of cellular respiration. 9.2 the process of cellular respiration answer key unit. Energy Extraction Energy released by the breaking and rearranging of carbon bonds is captured in the forms of ATP, NADH, and FADH2. 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. When you are hungry, how do you feel? Everything you want to read. Directions: Watch Cellular Processes: Electron Transport Chain and Cellular Processes: ATP Synthase to learn how electrons are passed through proteins in the electron transport chain and ATP is produced.
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: Watch for a general overview. If you like this these notes, you can follow these lin. These notes include Glycolysis, Oxidation of Pyruvate, Krebs Cycle, Oxidative Phosphorylation, and Anaerobic Respiration. Explain the relationship between chemiosmosis and proton motive force. 9.2 the process of cellular respiration answer key pogil. Glycolysis is the first set of reactions that occur during cellular respiration. 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 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. One possible alternative to aerobic respiration is anaerobic respiration, using an inorganic molecule other than oxygen as a final electron acceptor. The answer is cellular respiration. The cell lacks a sufficient amount of oxygen to carry out aerobic respiration.
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 Krebs Cycle During the Krebs cycle, the second stage of cellular respiration, pyruvic acid produced in glycolysis is broken down into carbon dioxide. 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. All in all, the breakdown of a single molecule of glucose yields 36 molecules of ATP. ATP is a source of usable energy for cells and is the key energy molecule for all biological organisms. There pyruvate feeds into the next stage of respiration, which is called the citric acid cycle (or Krebs cycle). Biology 2010 Student Edition Chapter 9, Cellular Respiration and Fermentation - 9.2 - The Process of Cellular Respiration - 9.2 Assessment - Page 260 4a | GradeSaver. 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). Pages 12 to 22 are not shown in this preview.
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+. However, anaerobic respirers use altered ETS carriers encoded by their genomes, including distinct complexes for electron transfer to their final electron acceptors. Also, 2 molecules of NADH are made. Directions: Watch the video Energy Consumption: An Overview for a look at the different cellular processes responsible for generating and consuming energy. The Advantages of Glycolysis Glycolysis produces ATP very fast, which is an advantage when the energy demands of the cell suddenly increase. Citric Acid Production Once pyruvic acid is in the mitochondrial matrix, NAD+ accepts 2 high-energy electrons to form NADH. We have just discussed two pathways in glucose catabolism—glycolysis and the Krebs cycle—that generate ATP by substrate-level phosphorylation. 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. Do both aerobic respiration and anaerobic respiration use an electron transport chain? 9.2 the process of cellular respiration answer key of life. Electron Transport System. Cellular Respiration Summary.
Can be used with Cornell notes. This 22 slide PowerPoint presentation covers 8 questions on the topic of cellular respiration. Microbes using anaerobic respiration commonly have an intact Krebs cycle, so these organisms can access the energy of the NADH and FADH2 molecules formed.
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. The remaining 64 percent is released as heat. 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. 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. Food serves as your source of energy. In aerobic respiration, the final electron acceptor (i. 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.
Glycolysis takes place in the cytoplasm of the cell. This electron carrier, cytochrome oxidase, differs between bacterial types and can be used to differentiate closely related bacteria for diagnoses. Cellular Respiration Overview. Glycolysis does not require oxygen, so it can quickly supply energy to cells when oxygen is unavailable. However, it usually results in the production of 36 ATP molecules. Directions: Watch The Citric Acid Cycle: An Overview to see how pyruvate is broken down during the citric acid cycle.
Energy Extraction Each molecule of glucose results in 2 molecules of pyruvic acid, which enter the Krebs cycle. For example, the number of hydrogen ions that the electron transport system complexes can pump through the membrane varies between different species of organisms. You're Reading a Free Preview. 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. A large amount of ATP is generated during this stage — 32 ATP molecules to be exact! 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.
These carriers can pass electrons along in the ETS because of their redox potential. Great for middle school or introductory high school courses. Compare and contrast the differences between substrate-level and oxidative phosphorylation. Equation for Cellular Respiration. Complex carbohydrates are broken down into simple sugars like glucose. Energy Extraction Citric acid is broken down into a 5-carbon compound and then a 4-carbon compound. Compare and contrast aerobic and anaerobic respiration. 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. For a protein or chemical to accept electrons, it must have a more positive redox potential than the electron donor. ATP Production H+ ions pass back across the mitochondrial membrane through the ATP synthase, causing the ATP synthase molecule to spin.
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. 16 summarizes the theoretical maximum yields of ATP from various processes during the complete aerobic respiration of one glucose molecule. Glycolysis Glycolysis - first stage of cellular respiration. Most ATP, however, is generated during a separate process called oxidative phosphorylation, which occurs during cellular respiration.
