Rate of enzymatic reaction is directly proportional to the concentration of:
Correct answer: B. Substrate
- A. Enzyme
- B. Substrate
- C. Enzyme and substrate
- D. Enzyme and product
Explanation
The rate of an enzymatic reaction is directly proportional to the concentration of substrate. This is because enzymes catalyze reactions by binding to substrates and converting them into products. When there is more substrate available, there are more opportunities for the enzyme to bind to substrate molecules and catalyze the reaction. However, once all enzyme molecules are saturated with substrate, increasing the enzyme concentration will not further increase the reaction rate. Therefore, the rate of enzymatic reaction is directly related to the concentration of substrate.

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.
