Question

In which of the following reactions of glycolysis, a molecule of water is removed from the substrate?

• A. Fructose-6-phosphate $ \rightarrow $ Fructose-1, 6-bisphosphate
• B. 3-phosphate-glyceraldehyde $ \rightarrow $ 1, 3 bisphosphoglyceric acid
• C. PEP $ \rightarrow $ Pyruvic acid
• D. 2- phosphoglycerate $ \rightarrow $ PEP

Answer 1

Answer: (D)

In the glycolysis process, the glucose undergoes partial oxidation and form 2 molecules of pyruvic acid. It is a chain of ten reactions that happen in the cytoplasm of the cell. In glycolysis, a water molecule is removed during the conversion of 2-phosphoglycerate to PEP.
