What happens when the co-factor is removed from the enzyme?
Options
- AThe catalytic activity increases.
- BThe catalytic activity remains unchanged.
- CThe catalytic activity decreases.
- DThe catalytic activity is lost.
Correct answer
D. The catalytic activity is lost.
Step-by-step solution
: A number of enzymes require metal ions for their activity which form coordination bonds with side chains at the active site and at the same time form one or more coordination bonds with the substrate, e.g., zinc is a cofactor for the proteolytic enzyme carboxypeptidase. Catalytic activity is lost when the co-factor is removed from the enzyme which testifies that they play a crucial role in the catalytic activity of the enzyme.
