Question

Hexokinase is an enzyme that binds specifically to glucose and converts it into glucose 6-phosphate. The activity of hexokinase is suppressed by glucose 6-phosphate, which binds to hexokinase at a location that is distinct from the active site. This is an example of what?

A. Feedback inhibition
B. Competitive inhibition
C. Cofactor binding
D. Allosteric activation

Answer 1

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.
