Answer:
A.
Step-by-step explanation:
Hexokinase in the main enzyme in glycolysis which converts glucose into glucose 6-phosphate (the first step of glycolysis).
2. The activity of hexokinase in regulated by some activators and inhibitors.
3. The activity of hexikinase is suppressed by glucose 6-phosphate, by feedback inhibition.
4. When the concentration of glucose 6-phosphate is increased in the cell, then it inhibits the activity of hexokinase by binding to hexokinase at a location that is distinct from the active site.
