Question

1. in beta oxidation, a 16 carbon fatty acid would give how many NADH? a) 7 b) 8 c) 9 d) 10

2. which enzyme is not replaced if gluconeogenesis is occurring instead of glycolysis? a) phosphofructokinase b) pyruvate kinase c) aldolase d) hekinase

3. phosphofructokinase is regulated by ____ in a negative manner. a) ADP b) NAD+ c) calcium d) citrate

4. how many NADH are oxidized in the electron transport chain from glycolysis under anaerobic conditions (per glucose)? a) 2 b) 3 c) 1 d) 0

5. phosphorylate of pyruvate dehydrogenase to inhibit the enzyme is in response to high levels of ___: a) NAD+ b) FAD c) ATP d) coenzyme A

6. which coenzyme accepts H: and helps with Bohr effect? a) NAD+ b) Thiamine pyrophosphate c) FAD d) lipoic acid

7. which amino acid in phosphofructokinase allows the substrate to bind? a) glutamic acid b) onithine c) citruilline d) arginine

Explanation / Answer

Ans- 1 the correct option is (A) i.e. 7 NADP

Because 16 carbon chain fatty acid gives 7 NADP during beta oxidation.

Ans-2 the correct option is (C) i.e. aldolase

because all the other enzymes are present in glycolysis only aldolase is present in gluconeogenesis.

Ans-3 the correct option is (A) i.e. ADP.

Because high ratio of ATP to ADP has an inhibitory action on the glycolysis

Ans-4 the correct option is (B) i.e. 3 NADP

The net NADP production from one cycle is 3 NADP.
