C) Some ATP is created through substrate-level phosphorylation. D) Overall, glycolysis releases energy and is thus termed^ exergonic. E) All of the above statements are true. 9 Where in a eukaryotic cell does pyruvate oxidation occur? A) In the mitochondrion. B) In the electron transport chain. C) In the cytoplasm, just like in prokaryotes. D) Anywhere in the cell, provided pyruvate dehydrogenase is present. E) In ribosomes. 10 The Krebs cycle is responsible for making most of the cell's ATP. A) True B) False 11 Which of the following is most directly responsible for creation of ATP at the mitochondrial inner membrane? A) NADH B) A proton gradient C) FADH 2 D) Movement of electrons along the membrane itself E) The activity of NADH dehydrogenase 12 Which of these is one of the correct reasons that less than the theoretical amount of ATP (36-
would have been released into the environment as photosynthesis occurred? A) Gaseous hydrogen B) Liquid hydrogen C) Water D) HS E) Sulfur Pre-Test Respiration The correct answer for each question is indicated by a. 1 Why does NAD
serve as important electron carrier? A) It is readily reduced and oxidized. B) It is insoluble and is stationary within the cell. C) It can accept electrons in a variety of positions along its length. D) It "protects" electrons from winding up in fatty acid precursors where the energy would be wasted. E) All of the above are correct. 2 What products result from the complete oxidation of glucose? A) CO B) ATP C) NADH D) FADH E) All of these result from glucose oxidation. 3 Why must NAD+^ be present during glycolysis? A) It creates pyruvate directly from glucose. B) A glycolysis intermediate must be oxidized in order to receive a phosphate so that substrate-level phosphorylation may occur. C) It powers the electron transport chain. D) It is a coenzyme which allows^ the 6 carbons of glucose to separate from each other, leading to two three-carbon products. E) This is a trick question: NAD
is only involved in the Krebs cycle. 4 What is/are the product(s) of pyruvate oxidation? A) O 2 B) Acetyl-CoA C) NAD
D) ATP E) All of the above are created during pyruvate oxidation 5 How many CO 2 molecules are released specifically from the Krebs cycle for each glucose molecule consumed?
