question 15 (1 point)
in which step of glycolysis is water produced?
○ step 4
○ step 6
○ step 7
○ step 9

Explanation:

In glycolysis, step 9 involves the conversion of 2 - phosphoglycerate to phosphoenolpyruvate (PEP) catalyzed by enolase. During this reaction, a molecule of water is produced as 2 - phosphoglycerate (which has a hydroxyl group and a phosphate group on adjacent carbons) undergoes a dehydration reaction to form PEP, releasing water. Step 4 is the cleavage of fructose - 1,6 - bisphosphate, step 6 is the oxidation of glyceraldehyde - 3 - phosphate, and step 7 is the transfer of a phosphate group, none of which produce water.

Answer:

step 9
