Question

multiple choice question
which of the following is an accurate description of a coenzyme?
organic molecules that temporarily attach to an enzyme and promote a chemical reaction without being changed during the reaction
small molecules permanently attached to the outside of an enzyme that aid in catalysis
small inorganic ions that temporarily attach to the outside of an enzyme and promote a chemical reaction

Explanation:

Coenzymes are organic non - protein molecules that temporarily bind to an enzyme. They assist in the enzyme - catalyzed reaction and remain unchanged at the end of the reaction. The second option is incorrect as coenzymes are not permanently attached. The third option is wrong because coenzymes are organic, not inorganic ions.

Answer:

Organic molecules that temporarily attach to an enzyme and promote a chemical reaction without being changed during the reaction
