The first step of cellular respiration in all organisms; “splitting of sugar” 48. Summary. The multistep chemical breakdown of a molecule of glucose into two molecules of pyruvic acid b. Electron transport takes place mitochondria of cell. c. the breakdown of an acetyl group to carbon dioxide. In the end, this process can produce up to 32-34 ATP molecules from one glucose molecule. The Electron Transport Chain takes place in the inter membrane space of the mitochondria. d. the breakdown of glucose into six carbon dioxide molecules Select one: a. energy is stored in the form of NADH. Section: 9.4 As a result of these reactions, the proton gradient is produced, enabling mechanical work to be converted into chemical energy, allowing ATP synthesis. The simplest way to understand this, is that it basically moves the electrons from high energy to low energy. a. ANSWER: Chapter 6 - Question 29 - Multiple Choice Part A Aerobic cellular respiration generates about _____ ATP from one glucose. Which of the following events takes place in the electron transport chain? C) the extraction of energy from high-energy electrons remaining from glycolysis and the citric acid cycle. Respiration can be split into 3 main processes, Glycolysis, Krebs cycle (Tricarboxylic Acid / Citrate Acid Cycle) and the Electron Transport Chain. B) the breakdown of an acetyl group to carbon dioxide. The third stage, electron transport, takes place on the inner membrane. C.) cytoplasm. D.) ribosomes. chloroplasts. b. the harnessing of energy from high-energy electrons derived from glycolysis and the citric acid cycle. Electron transport takes place in the _____. mitochondria. Mitochondria. Answers: 2, question: Which of the following events takes place in the electron transport chain? A) the breakdown of glucose into two pyruvate molecules. Cellular respiration takes the energy stored in glucose and transfers it to ATP. Electron transport takes place in the: A.)

a) the breakdown of glucose into two pyruvate molecules
b) the breakdown of an acetyl group to carbon dioxide
c) the extraction of energy from high-energy electrons remaining from glycolysis and the citric acid cycle
d) substrate-level phosphorylation This process can only function if there is oxygen available. D. electron transport Cellular Respiration: To ensure that energy needs of the cells are met, living cells break down food molecules through the process of cellular respiration. The electron transport chain is a series of transmembrane proteins found in the inner membrane. ANSWER: 32 The number generated depends on whether the end product of aerobic respiration is lactic acid or ethyl alcohol. ANSWER: Chapter 6 - Question 28 - Multiple Choice Part A ATP synthase plays a role in _____. The electron transport chain involves a series of redox reactions that relies on protein complexes to transfer electrons from a donor molecule to an acceptor molecule. How much energy is made from cellular respiration? The inner mitochondrial membrane. B.) Mitochondria is known as the powerhouse of the cell. a. D) substrate-level phosphorylation. Where does it glycolysis occur? Electron transport chain takes place in the mitochondrion inner membrane and electrons are transferred from one protein complex to another in the order of their increasing reduction potentials. 32 ATP 47. The electrons are shuttled between these proteins which is used to pump protons (H^+) to the space between the inner and the outer membrane. electron transport takes place in the grana of the chloroplast during light reaction. Which of the following events takes place in the electron transport chain? c. Electron Transport Phosphorylation takes place in the inner membrane of the mitochondrion 46. Cellular respiration has three stages: glycolysis: the Krebs cycle and electron transport. The mitochondrion has an outer membrane and an inner membrane with folds (cisternae). What is glycolysis?
