Question

multiple choice question

typically, the presence of enzymes ______ the activation energy needed for a reaction to proceed.

• stays the same
• increases
• lowers

Explanation:

Identify the role of enzymes in chemical reactions

$$ \text{Enzymes} = \text{Biological Catalysts} $$

Determine the effect on activation energy

$$ \text{Catalysis} \implies \text{Lowering of Activation Energy } (E_a) $$

Match with the given multiple-choice options

$$ \text{Option 3: "lowers"} \implies \text{Correct choice} $$

Answer:

• stays the same
• increases
• lowers (Correct answer)
