Answer 1

16). Option C is correct. Explanation: L-lactate dehydrogenase (L-LDH) catalyzes the interconversion of pyruvate and NADH+ to L-lactate and NAD+. 17). Option D is correct. Explanation: Lactate dehydrogenase is responsible for the anaerobic conversion of NADH to NAD+ in the anaerobic glycolysis for the production of ATP. 18). Option C is correct. Explanation: The phosphagen system converts the ADP into ATP with the help of an enzyme creatine kinase. 19). Option C is correct. Explanation: The Phosphagen production system uses creatine phosphate for the production of ATP. The creatine is used for the reconstitution of the ATP after its break down to release its energy.
