Apoenzyme

Description:

An apoenzyme, also known as an inactive enzyme, is a protein component of an enzyme that is incapable of catalyzing a chemical reaction on its own. It requires the binding of a coenzyme or a cofactor to become functional and initiate the catalytic activity.

Senses:

• 1. Noun - The protein component of an enzyme that lacks catalytic activity until combined with a coenzyme or cofactor.
• 2. Noun - The inactive form of an enzyme, which requires a non-protein component to become effective in catalyzing reactions.

Sample Sentences:

• 1. The apoenzyme's function is activated only after it binds to its required coenzyme.
• 2. The reaction could not occur until the apoenzyme united with the necessary cofactor.
• 3. The apoenzyme alone lacked the ability to produce the desired product.
