What combines with inactive enzymes to form active enzymes able to catalyze specific reactions?Multiple choice question.CofactorsProvitaminsCoagulants

Break Down the Problem

1. Identify the role of each option in relation to enzymes.
2. Determine which option combines with inactive enzymes to activate them.

Relevant Concepts

• Cofactors: Non-protein molecules that assist enzymes in catalyzing reactions.
• Provitamins: Substances that are converted into vitamins in the body, but do not directly activate enzymes.
• Coagulants: Substances that promote coagulation or clotting, usually related to blood, not enzyme activation.

Analysis and Detail

1. Cofactors are essential for the activation of many enzymes. They can be metal ions (like zinc or magnesium) or organic molecules (like coenzymes).
2. Provitamins do not directly interact with enzymes; instead, they serve as precursors to vitamins.
3. Coagulants are not related to enzyme activity but are important in the blood clotting process.

Verify and Summarize

Given the definitions, it is clear that the option that combines with inactive enzymes to form active enzymes is Cofactors.

Final Answer

The correct answer is Cofactors.
