Question

In glycolytic pathway, which of the following steps shows reduction of coenzyme?

• A. 1, 3 – diphosphoglycerate to 3 – phosphoglycerate
• B. Glucose - 6 – phosphate to fructose- 6 – phosphate
• C. 3 – phosphoglycerate to 2 – phosphoglycerate
• D. Glyceraldehyde - 3 – phosphate to 1, 3 - diphosphoglycerate

Answer 1

The correct option is D Glyceraldehyde - 3 – phosphate to 1, 3 - diphosphoglycerate

In glycolysis pathway, glyceraldehyde-3-phosphate is converted to 1, 3-diphosphoglycerate. In this step, $NA{D}^{+}$is reduced to $NAD{H}_2$. Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in all living cells. So, the correct answer is 'Glyceraldehyde-3-phosphate to 1,3-diphosphoglycerate'.
