When you eat, your body digests the food into smaller chemical compounds like sugars (glucose), fats, and proteins. Weakness is your body's way of telling you that your energy supplies are low. Pages 12 to 22 are not shown in this preview. Everything you want to read. What are the functions of the proton motive force? The cell lacks a sufficient amount of oxygen to carry out aerobic respiration. You're Reading a Free Preview. 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. 9.2 the process of cellular respiration answer key worksheet. 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. Explain the relationship between chemiosmosis and proton motive force. Great for middle school or introductory high school courses. Two molecules of CO2 are released. This represents about 36 percent of the total energy of glucose.

One molecule of CO2 is also produced. Cellular Respiration Summary. 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. These nutrients enter your cells and are converted into adenosine triphosphate ( 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. 9.2 the process of cellular respiration answer key answers. Energy Totals The cell can generate ATP from just about any source, even though we've modeled it using only glucose. 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:

9.2 The Process Of Cellular Respiration Answer Key Answers

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. Glucose is broken down into 2 molecules of pyruvic acid, which becomes a reactant in the Krebs cycle. The remaining 2 carbon atoms react to form acetyl-CoA. Citric Acid Production Once pyruvic acid is in the mitochondrial matrix, NAD+ accepts 2 high-energy electrons to form NADH. The remaining 64 percent is released as heat. 9.2 the process of cellular respiration answer key 2018. Energy Extraction Energy released by the breaking and rearranging of carbon bonds is captured in the forms of ATP, NADH, and FADH2. Denitrifiers are important soil bacteria that use nitrate and nitrite as final electron acceptors, producing nitrogen gas (N2).

9.2 The Process Of Cellular Respiration Answer Key Answer

Along the way, ATP (energy for cells) is produced. Food serves as your source of energy. 2 ATP are usually required to bring the pyruvic acid into the matrix. Biology 2010 Student Edition Chapter 9, Cellular Respiration and Fermentation - 9.2 - The Process of Cellular Respiration - 9.2 Assessment - Page 260 4a | GradeSaver. 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). Glycolysis is the first set of reactions that occur during cellular respiration. 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.

ATP Production H+ ions pass back across the mitochondrial membrane through the ATP synthase, causing the ATP synthase molecule to spin. Equation for Cellular Respiration. Compare and contrast aerobic and anaerobic respiration. This electron carrier, cytochrome oxidase, differs between bacterial types and can be used to differentiate closely related bacteria for diagnoses. 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. However, it usually results in the production of 36 ATP molecules. These notes include Glycolysis, Oxidation of Pyruvate, Krebs Cycle, Oxidative Phosphorylation, and Anaerobic Respiration. Smaller electrochemical gradients are generated from these electron transfer systems, so less ATP is formed through anaerobic respiration.

9.2 The Process Of Cellular Respiration Answer Key Sample

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. Glycolysis Glycolysis - first stage of cellular respiration. At this point, try not to worry about the names of compounds or the details of the processes shown. Glycolysis is an anaerobic process, meaning it occurs without oxygen. 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. 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. Most ATP, however, is generated during a separate process called oxidative phosphorylation, which occurs during cellular respiration. Energy Totals In the presence of oxygen, the complete breakdown of glucose through cellular respiration could produce 38 ATP molecules. Cellular Respiration Overview. Microbes using anaerobic respiration commonly have an intact Krebs cycle, so these organisms can access the energy of the NADH and FADH2 molecules formed. 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). 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. There are many types of anaerobic respiration found in bacteria and archaea. The electron transport chain (ETC) is the final stage of cellular respiration.

9.2 The Process Of Cellular Respiration Answer Key 2018

Overall, 2 molecules of ATP are produced. I tried my best to visually layout the metabolic pathways of Cellular Respiration for my AP Biology students. Energy Extraction Citric acid is broken down into a 5-carbon compound and then a 4-carbon compound. Cellular Respiration: The Citric Acid Cycle (or Krebs Cycle). Compare and contrast the differences between substrate-level and oxidative phosphorylation. Learning Objectives. So each molecule of glucose results in two complete "turns" of the Krebs cycle. 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. 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. 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. Energy Extraction Each molecule of glucose results in 2 molecules of pyruvic acid, which enter the Krebs cycle. Reward Your Curiosity. There pyruvate feeds into the next stage of respiration, which is called the citric acid cycle (or Krebs cycle).

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). 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. 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. Cellular Respiration: Glycolysis. One possible alternative to aerobic respiration is anaerobic respiration, using an inorganic molecule other than oxygen as a final electron acceptor.

Can be used with Cornell notes. Electron Transport System. ATP is a source of usable energy for cells and is the key energy molecule for all biological organisms.
