Prosthetic groups are:
Correct answer: B. Organic molecules
- A. Metallic ions
- B. Organic molecules
- C. Inorganic molecules
- D. Radicals
Explanation
Cofactors are substances that help enzymes function properly. Inorganic cofactors act as activators, while organic cofactors can be either coenzymes or prosthetic groups. Generally, prosthetic groups are organic molecules that remain tightly bound to the enzyme. However, they may sometimes be inorganic in nature, such as metallic ions. It is important to note that prosthetic groups are not free radicals.

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.
