The first step in glycolysis is the transfer of the phosphate group from ATP to glucose. Which product is formed by this reaction?
Correct answer: B. Glucose-6-Phosphate
- A. Fructose-6-Phosphate
- B. Glucose-6-Phosphate
- C. Fructose-1,6 biphosphate
- D. Dihydroxyacetone phosphate
Explanation
A. Glucose-6 phosphate is converted into its isomer fructose -6-phosphate, by an isomerase enzyme.C. A molecule of ATP is transferred to Fructose -6-Phosphate to form itD. Fructose 1,6 biphosphate splits up into glyceraldehyde 3 phosphate and dihydroxyacetone 3 phosphate.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
