A. electron transport, and it occurs in the cytosol. B. electron transport, and it occurs in the mitochondria. C. glycolysis, and it occurs in the cytosol. D. glycolysis, and it occurs in the mitochondria. E. the citric acid cycle, and it occurs at the mitochondria. (Question 2) Phosphorylation is carried out by a A. kinase, and it results in the negative feedback inhibition of an enzyme. B. kinase, and it may activate some enzymes and inhibit others. C. phosphatase, and it results in the negative feedback inhibition of an enzyme. D. phosphatase, and it may activate some enzymes and inhibit others. (Question 3) magine that you discovered an enzyme in the human stomach that turned the substrate ABC into the product XYZ. Name this enzyme (using the standard convention) and describe its chemical characteristics. Under what conditions would it be an effective catalyst? How might its activity be regulated? What will be an ideal response? (Question 4) A protein kinase is an enzyme that adds a phosphate to its substrate. Indicate whether this statement is true or false. (Question 5) Enzymes that remove phosphate groups from their substrates are called __________. Fill in the blank with correct word. (Question 6) Enzyme regulation by negative feedback involves A. allosteric inhibition of an enzyme by a product of its metabolic pathway. B. allosteric facilitation of an enzyme by a substrate of its metabolic pathway. C. allosteric modification of a substrate by an enzyme of an alternate metabolic pathway. D. occupation of the active site of an enzyme so that it catalyzes less efficiently. E. enhancement of the active site by a negatively charged substrate. (Question 7) In the regulation of enzymes, negative feedback ensures that a lot of product can be made from only a little bit of substrate. Indicate whether this statement is true or false. (Question 8) To prevent depletion of a substrate, the product of a metabolic pathway will A. turn off an enzyme early in the pathway. B. catalyze its own production. C. increase enzyme activity through positive feedback. D. occupy the active site of an enzyme early in the pathway. (Question 9) Which enzyme system allows for regulation at a single site and also diminishes the chance that a needed substrate will diffuse away from a catalyst? A. Metabolic pathway B. Multienzyme complex (Question 10) A group of enzymes that are physically attached to one another is referred to as a(n) A. allosteric pathway. B. metabolic pathway. C. multienzyme complex. D. phosphate complex. Title: The first stage of cellular respiration is Post by: jamestopranked on Feb 22, 2018 Content hidden
