Multiple Choice

Which of the following is an accurate description of a coenzyme?

A coenzyme is a protein that acts as a catalyst in biochemical reactions.

A coenzyme is a non-protein compound that is necessary for the functioning of an enzyme.

A coenzyme is a substrate that is converted into a product by an enzyme.

A coenzyme is a type of enzyme that is permanently attached to the active site.

Verified step by step guidance

Understand the role of a coenzyme: A coenzyme is a non-protein compound that assists enzymes in catalyzing reactions. It is not a protein itself, but it is essential for the enzyme's activity.

Differentiate between coenzymes and enzymes: Enzymes are proteins that act as catalysts in biochemical reactions, whereas coenzymes are organic molecules that bind to enzymes and help them function.

Clarify the relationship between coenzymes and substrates: Coenzymes are not substrates. Substrates are the molecules upon which enzymes act, while coenzymes assist in the reaction but are not converted into products.

Distinguish between coenzymes and prosthetic groups: Coenzymes are not permanently attached to enzymes. They can bind temporarily during the reaction, unlike prosthetic groups, which are permanently attached.

Identify the correct description: The accurate description of a coenzyme is that it is a non-protein compound necessary for the functioning of an enzyme, as it helps facilitate the enzyme's catalytic activity.
