Enzymes __________________ the activation energy of a chemical reaction?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Does not effect
- D. Increases or decreases depending upon individual enzyme
Explanation
Enzymes decrease activation energy by providing an alternative reaction pathway, allowing more molecules to react at a given temperature. A student may choose d because enzymes can affect reaction rates in different ways, but catalysts do not increase activation energy, and the net enzyme effect is its reduction.
