The enzyme, which forms glucose -6- phosphate, is:
Correct answer: C. Hexokinase
- A. Phosphorylase
- B. Phosphatase
- C. Hexokinase
- D. Gluco-synthetase
Explanation
Hexokinase is an enzyme that catalyzes the phosphorylation of glucose or other hexoses (six-carbon sugars) to produce hexose phosphate. This phosphorylation is the first step in the process of glycolysis, a central pathway in cellular metabolism that involves the breakdown of glucose to produce energy in the form of ATP.

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.
