6 Multiple Choice Questions
- The conversion of pyruvate from glycolysis to carbon dioxide and ethyl alcohol
- An enzyme that catalyzes a chemical reaction during which one or more hydrogen atoms are removed from a molecule
- An organism that only carries out fermentation; such organisms cannot use oxygen and also may be poisoned by it.
- Energy-coupling mechanics that uses the energy of hydrogen ion gradients across membranes to phosphorylate ADP; powers most ATP synthesis in cells
- The conversion of pyruvate to lactate with no release of carbon dioxide.
- The formation of ATP by an enzyme directly transferring a phosphate group to ADP from an organic molecule
6 True/False Questions
oxidative phosphorylation → The production of ATP using energy derived from the redox reactions of an electron transport chain; the third major stage of cellular respiration
citric acid cycle → The entry compound for the citric acid cycle in cellular respiration; formed from a fragment of pyruvate attached to a coenzyme
redox reaction → The gain of electrons by a substance involved in a redox reaction; always accompanies oxidation
reduction → The loss of electrons from a substance involved in a redox reaction; always accompanies reduction
glycolysis → a quantity of heat equal to 1,000 calories. Used to measure the energy content of food, it is usually called a "Calorie"
intermediates → One of the compounds that form between the initial reactant and the final product in a metabolic pathway, such as between glucose and pyruvate in glycolysis
