The catalytic activity of an enzyme is enhanced by?
Correct answer: D. Both A and B
- A. Activator
- B. Coenzyme
- C. Co-factor
- D. Both A and B
Explanation
Following are definitions of each of the above terms: Coenzyme: A substance that enhances the action of an enzyme. (An enzyme is a protein that functions as a catalyst to mediate and speed a chemical reaction). Coenzymes are small molecules. They cannot by themselves catalyze a reaction but they can help enzymes to do soCofactors: can be metals or small organic molecules, and their primary function is to assist (not enhance) in enzyme activity. They are able to assist in performing certain, necessary, reactions the enzyme cannot perform alone. Activators: Enzyme activators are chemical compounds that increase a velocity (enhances) of enzymatic reaction

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
