Question

In TCA cycle the hydrogen atom removed at succinate level are accepted by ____________while in hexose monophosphate shunt,the hydrogen acceptor is __________

• A. CoA, NAD
• B. FAD NADP
• C. GTP,NAD
• D. O2,Fd

Answer 1

Answer:

B. FAD NADP

• In TCA cycle: FAD

• In hexose monophosphate shunt (Pentose Phosphate Pathway): NADP

1. TCA cycle: During the conversion of succinate to fumarate, FAD (Flavin Adenine Dinucleotide) accepts the hydrogen atoms, forming FADH2.

2. Hexose monophosphate shunt: In this pathway, NADP+ (Nicotinamide Adenine Dinucleotide Phosphate) acts as the hydrogen acceptor, getting reduced to NADPH.
