Question

Quizplus · Accepted Answer

Coenzymes are organic molecules derived from vitamins, such as coenzyme A derived from vitamin B5. They often act as helpers to enzymes, allowing them to perform their functions more efficiently. Coenzymes are not enzymes themselves and are chemically changed over the course of a reaction. They are not found exclusively in bacterial cells and can also be found in eukaryotic cells. The statement "oxidoreductases" is not a suitable description of coenzymes as it is a type of enzyme that catalyzes redox reactions.
