Electron Transport System. Glucose is broken down into 2 molecules of pyruvic acid, which becomes a reactant in the Krebs cycle. 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.
Explain the relationship between chemiosmosis and proton motive force. I also think that even if you don't use fill-in-the. 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. Complex carbohydrates are broken down into simple sugars like glucose. The number of ATP molecules generated from the catabolism of glucose varies. 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. The electron transport chain (ETC) is the final stage of cellular respiration. 9.2 the process of cellular respiration answer key pdf. For example, the number of hydrogen ions that the electron transport system complexes can pump through the membrane varies between different species of organisms. Energy Extraction Each molecule of glucose results in 2 molecules of pyruvic acid, which enter the Krebs cycle. Glycolysis takes place in the cytoplasm of the cell. Cellular Respiration: Electron Transport Chain. 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.
One molecule of CO2 is also produced. 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. The cell lacks a sufficient amount of oxygen to carry out aerobic respiration. A large amount of ATP is generated during this stage — 32 ATP molecules to be exact! Chemiosmosis, Proton Motive Force, and Oxidative Phosphorylation. Reward Your Curiosity. Citric Acid Production Pyruvic acid from glycolysis enters the matrix, the innermost compartment of the mitochondrion. Energy Totals The cell can generate ATP from just about any source, even though we've modeled it using only glucose. Biology 2010 Student Edition Chapter 9, Cellular Respiration and Fermentation - 9.2 - The Process of Cellular Respiration - 9.2 Assessment - Page 260 4a | GradeSaver. However, it usually results in the production of 36 ATP molecules. The remaining 2 carbon atoms react to form acetyl-CoA. 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. Most ATP, however, is generated during a separate process called oxidative phosphorylation, which occurs during cellular respiration.
This represents about 36 percent of the total energy of glucose. Directions: Watch the video Energy Consumption: An Overview for a look at the different cellular processes responsible for generating and consuming energy. 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 does not require oxygen, so it can quickly supply energy to cells when oxygen is unavailable. The remaining 64 percent is released as heat. These notes include Glycolysis, Oxidation of Pyruvate, Krebs Cycle, Oxidative Phosphorylation, and Anaerobic Respiration. 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. 2 ATP are usually required to bring the pyruvic acid into the matrix. 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. Citric Acid Production Acetyl-CoA combines with a 4-carbon molecule to produce citric acid. 9.2 the process of cellular respiration answer key.com. Directions: Watch Glycolysis: An Overview to see how glucose is broken down during the process of glycolysis. 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).
The answer is cellular respiration. I tried my best to visually layout the metabolic pathways of Cellular Respiration for my AP Biology students. These ATP molecules come from glycolysis, the Krebs cycle, and the electron transport chain. 9.2 the process of cellular respiration answer key question. Two molecules of CO2 are released. The tendency for movement in this way is much like water accumulated on one side of a dam, moving through the dam when opened. Smaller electrochemical gradients are generated from these electron transfer systems, so less ATP is formed through anaerobic respiration. Great for middle school or introductory high school courses. 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.
At this point, try not to worry about the names of compounds or the details of the processes shown. The Krebs Cycle During the Krebs cycle, the second stage of cellular respiration, pyruvic acid produced in glycolysis is broken down into carbon dioxide. 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: If you like this these notes, you can follow these lin. 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. But how does the food you eat get converted into a usable form of energy for your cells? There are many types of anaerobic respiration found in bacteria and archaea. All in all, the breakdown of a single molecule of glucose yields 36 molecules of ATP. When you eat, your body digests the food into smaller chemical compounds like sugars (glucose), fats, and proteins. Also, 2 molecules of NADH are made.
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. What are the functions of the proton motive force? 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. Energy Totals In the presence of oxygen, the complete breakdown of glucose through cellular respiration could produce 38 ATP molecules. Lipids and proteins can be broken down into molecules that enter the Krebs cycle or glycolysis at one of several places. 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. 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 Krebs cycle is also known as the citric acid cycle because citric acid is the first compound formed in this series of reactions. These nutrients enter your cells and are converted into adenosine triphosphate ( ATP). Carbons are broken down and released as carbon dioxide while ATP is made and electrons are passed to electron carriers, NADH and FADH2.
Describe the function and location of ATP synthase in a prokaryotic versus eukaryotic cell. It's actually quite amazing. The NADH carries high-energy electrons to the electron transport chain, where they are used to produce ATP. 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. Cellular Respiration: Glycolysis. Along the way, ATP (energy for cells) is produced.
