Determine whether cellular respiration is an endergonic or exergonic process. Explain your answer. b) List the reactants and products for the process given i) Glycolysis. Reactants: Products (net): i) Citric acid cycle. Reactants: Products: c) How is ATP produced during Glycolysis and Citric acid cycle? d) Describe the process of ATP production by ATP synthase in oxidative phosphorylation.arrow_forwardDiscuss the composition of the transition state for the formation of ATP by ATP Synthase. a) Where is the active site for this enzyme located? b) How are the amino acid side chains from the α and β subunits of ATP Synthase involved? c) Discuss the importance of Mg+2 in the mechanism of this enzyme.arrow_forward
- Indicate whether the following statements are true or false:- a) The pentose phosphate pathway of glucose oxidation can lead to the release of energy. b) NAD + is a coenzyme of transketolase.arrow_forwardDetermine whether the following statements are true or false:- a) The pentose phosphate pathway of glucose conversion is a supplier of NADPH (H +) for reductive syntheses. b) An overdose of insulin causes hypoglycemia in a patient with diabetes mellitus. c) Fructose-6-phosphate is an allosteric regulator of glycolysis.arrow_forwardDuring the metabolism of glucose in anaerobic cells, the enzyme lactate dehydrogenase is essential to allow glycolysis to continue. This enzyme catalyzes the reduction of pyruvate to lactate. Why is this so essential? OA) It lowers the pH. B) It re-oxidizes NADH to NAD+. C) Lactate stimulates hexokinase activity. D) Pyruvate inhibits pyruvate kinase.arrow_forward
