Question

Which of the following can increase the rate of a biochemical reaction?

a) Increase the temperature
b) Increase the concentrations of the reactants
c) Increase or decrease the pH
d) Add a catalyst

Answer 1

Increasing the rate of a biochemical reaction can be achieved by increasing the temperature, and the concentrations of the reactants, or adding a catalyst. The options (A), (B), and (D) are correct.

Step-by-step explanation:

Increasing the rate of a biochemical reaction can be achieved through several factors:

1. Increasing the temperature: Generally, an increase in temperature increases the rate of a chemical reaction because more molecules have energy than activation energy at higher temperatures.
2. Increasing the concentrations of the reactants: An increase in the concentration of reactants increases the frequency of collisions, leading to a higher reaction rate.
3. Adding a catalyst: Catalysts increase the rate of chemical reactions by providing an alternative pathway with a lower activation energy.

Therefore, options (A), (B), and (D) are correct.
