On which of the following factors rate of enzyme action is directly proportional?
Correct answer: C. Concentration of substrate
- A. Concentration of products
- B. Time
- C. Concentration of substrate
- D. Concentration of solvent
Explanation
The rate of enzyme action is directly proportional to the concentration of the substrate. This is because the more substrate there is, the more enzyme molecules can bind to it and catalyze the reaction. The rate of enzyme action is not directly proportional to the concentration of products, time, or concentration of solvent.

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.
