What alters the shape of enzymes and makes them functional.
Correct answer: A. Cofactors
- A. Cofactors
- B. Other enzymes
- C. Proteins
- D. Both a and c
Explanation
Cofactors are non-protein chemical compounds or metallic ions that bind to an enzyme and are essential for the enzyme's activity. They help stabilize the enzyme structure or participate in the enzyme's catalytic function, thereby altering the enzyme's shape to make it functional.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
