Question

The steps of glycolysis between glyceraldehyde-3-phosphate and 3-phosphoglycerate involve all of the following except:A. ATP synthesisB. Utilization of PiC. Oxidation of NADH to NAD+.D. The formation of 1,3-Bisphosphoglycerate.E. Catalysis by Phosphoglycerate Mutase.

Answer 1

Answer:

Option(C)- Oxidation of NADH to NAD+H

Explanation:

• In glycolysis at the step between formation of 3-phosphoglyceraldehyde from glyceraldehyde 3-phosphate, NAD+H is reduced to form NADH(where NAD stands for nicotinamide-adenine dinucleotide) which means a hydrogen atom is added in NAD forming NADH.
• This enters in elecron transport chain (etc) in mitochondrial membrane which ultimately helps in production of ATP.
• Hence all other options are true except option C.

Result: Therefore option C is the correct answer.
