Energy Extraction Citric acid is broken down into a 5-carbon compound and then a 4-carbon compound. 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. Two molecules of CO2 are released. One possible alternative to aerobic respiration is anaerobic respiration, using an inorganic molecule other than oxygen as a final electron acceptor. The Advantages of Glycolysis Glycolysis produces ATP very fast, which is an advantage when the energy demands of the cell suddenly increase. Most ATP, however, is generated during a separate process called oxidative phosphorylation, which occurs during cellular respiration. We have just discussed two pathways in glucose catabolism—glycolysis and the Krebs cycle—that generate ATP by substrate-level phosphorylation. 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, 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. ATP Production H+ ions pass back across the mitochondrial membrane through the ATP synthase, causing the ATP synthase molecule to spin. However, anaerobic respirers use altered ETS carriers encoded by their genomes, including distinct complexes for electron transfer to their final electron acceptors. 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. 2 The Process of Cellular Respiration.

9.2 The Process Of Cellular Respiration Answer Key Of Life

Citric Acid Production Acetyl-CoA combines with a 4-carbon molecule to produce citric acid. 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. Do both aerobic respiration and anaerobic respiration use an electron transport chain? Cellular Respiration Overview. 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. 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. Energy Totals The cell can generate ATP from just about any source, even though we've modeled it using only glucose. Lipids and proteins can be broken down into molecules that enter the Krebs cycle or glycolysis at one of several places. Learning Objectives. Directions: Watch Glycolysis: An Overview to see how glucose is broken down during the process of glycolysis. 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.

There pyruvate feeds into the next stage of respiration, which is called the citric acid cycle (or Krebs cycle). Cellular Respiration: The Citric Acid Cycle (or Krebs Cycle). 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. Citric Acid Production Once pyruvic acid is in the mitochondrial matrix, NAD+ accepts 2 high-energy electrons to form NADH. In prokaryotic cells, H+ flows from the outside of the cytoplasmic membrane into the cytoplasm, whereas in eukaryotic mitochondria, H+ flows from the intermembrane space to the mitochondrial matrix.

The Krebs cycle is also known as the citric acid cycle because citric acid is the first compound formed in this series of reactions. This 22 slide PowerPoint presentation covers 8 questions on the topic of cellular respiration. Glycolysis takes place in the cytoplasm of the cell. At the end of the electron transport chain, the electrons combine with H+ ions and oxygen to form water. These notes include Glycolysis, Oxidation of Pyruvate, Krebs Cycle, Oxidative Phosphorylation, and Anaerobic Respiration. When you are hungry, how do you feel? 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. Can be used with Cornell notes. So each molecule of glucose results in two complete "turns" of the Krebs cycle.

Simple and easy to use. Energy Extraction Each molecule of glucose results in 2 molecules of pyruvic acid, which enter the Krebs cycle. Directions: Watch the video Energy Consumption: An Overview for a look at the different cellular processes responsible for generating and consuming energy. This electron carrier, cytochrome oxidase, differs between bacterial types and can be used to differentiate closely related bacteria for diagnoses. 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. What are the functions of the proton motive force? Energy Extraction Energy released by the breaking and rearranging of carbon bonds is captured in the forms of ATP, NADH, and FADH2. 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). Cellular Respiration Summary. Glycolysis does not require oxygen, so it can quickly supply energy to cells when oxygen is unavailable. Describe the function and location of ATP synthase in a prokaryotic versus eukaryotic cell. 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. Microbes using anaerobic respiration commonly have an intact Krebs cycle, so these organisms can access the energy of the NADH and FADH2 molecules formed.

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. 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: Denitrifiers are important soil bacteria that use nitrate and nitrite as final electron acceptors, producing nitrogen gas (N2). 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. A large amount of ATP is generated during this stage — 32 ATP molecules to be exact! Compare and contrast the differences between substrate-level and oxidative phosphorylation. With each rotation, the ATP synthase attaches a phosphate to ADP to produce ATP. 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.

You're Reading a Free Preview. Equation for Cellular Respiration. Energy Totals In the presence of oxygen, the complete breakdown of glucose through cellular respiration could produce 38 ATP molecules. 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 remaining 2 carbon atoms react to form acetyl-CoA. If you like this these notes, you can follow these lin.

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. The answer is cellular respiration. When you eat, your body digests the food into smaller chemical compounds like sugars (glucose), fats, and proteins. 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. 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.
