Question

How does an enzyme change the activation energy for a reaction in a cell?

a. Enzyme increases the activation energy
b. Enzyme does not affect the activation energy
c. Enzyme lowers the activation energy.

Answer 1

The correct answer is option c. "Enzyme lowers the activation energy".

Step-by-step explanation:

The activation energy is defined as the amount of energy needed for a reaction to take place. Enzymes catalyze reactions by lowering the activation energy, which speeds up the reaction and increases its rate. Enzymes put a substrate in its active site, which facilitates the reaction and makes more likely that it collides with its subsequent substrate.
