The correct option is A 1,3-bisphosphoglycerate
Oxidation of 3-Phosphoglyceraldehyde
The pathway of the breakdown of glucose into pyruvic acid is termed as glycolysis.
During the sixth step, 3-phosphoglyceraldehyde is oxidized to 1,3-bisphsosphoglycerate in presence of enzyme glyceraldehyde-3-phosphate dehydrogenase. During this reaction, NAD+ is converted to NADH.
Final answer: (A) 1,3-bisphosphoglycerate
