Question

can you check my answers

1. Which of the following steps or processes in aerobic respiration DIRECTLY consume molecular oxygen (O2)? a. Glycolysis. b. Oxidative decarboxylation of pyruvate. c. The citric acid cycle. d. Oxidative phosphorylation Beta-oxidation 2- Gluconeogenesis is a[n) pathway a condensation. b. catabolic (c) anabolic d. amphibolic e. photosynthetic 3. Because it is a degradative pathway that also generates biosynthetic precursors, the citric acid cycle is an) pathway. a. condensation 6 catabolic c. anabolic d. amphibolic e. photosynthetic 4. Unlike direct combustion, cellular respiration a. is a stepwise process b. requires multiple low activation energies (©) releases energy gradually, in forms and amounts that are usable d. All of the above e. None of the above 5. During which phase (s) of glycolysis is energy consumed as ATP? a. Phase 1. Phase 2. c. Phase 3. d. Phases 1 and 2 e. Phases 2 and 3.

Answer 1

1. A. Glycolysis because cellular respiration utilize energy in glucose to form Atp. Three process that utlize directly O2 are namely glycolysis, kreb cycle and electron transport chain.

2. C. Anabolic pathway because when liver and kidney produce glucose from noncarbhohydrate source.

3. C. Catabolic pathway because it utlize the acetyl coA as rate limiting utilizing nadh for energy source to form atp.

4. D. All the above because cellular respiration is a step wise process were glycolysis followed by kreb cycle then oxidative phosphorylation as it is...were in TCA cycle and oxidative phosphorylation it require low level of energy for activation and it releases energy gradually that ATP gets captured by electron transport chain in different steps and utilize energy molecules.

5. A. Phase 1(step 1) were in glycolysis first phase require engery for converting glucose to glucose 6 phosphate and for fructose 6 phosphate to fructose 1,6 phosphate utilize atp to form them.
