Question

The inorganic catalyst attached to an enzyme is called

• A. Apo-enzyme
• B. Lysozyme
• C. Activator
• D. Inhibitor

Answer 1

The correct option is C

Activator

The correct option is option (C):

Explanation of the correct option:

1. An activator is an inorganic catalyst molecule that binds to the enzyme and increases its activity.
2. Hence activator enhances the rate of reaction.
3. An activator molecule can bind to an enzyme and alter its overall shape.
4. This transformation improves the enzyme's ability to bind to its substrate and thereby speeds up the reaction.

The explanation for incorrect options:

Option (A):

The protein part of the enzyme is called apoenzyme.

Option (B):

Lysozyme is an enzyme that is commonly found in bodily secretions such as tears, saliva, and human milk, also called colostrum.

Option (D):

The molecule which inhibits the activity of the enzyme is called inhibitor.

Final answer: An activator is an inorganic catalyst molecule, which attaches to the enzyme to increase its activity and impacts the rate of reaction.
