alleryEnzymes speed a reaction by lowering its:
AActivation energy
BAbsorption energy
CAdsorption energy
DAttraction energy
Answer & Solution
Correct answer: A. Activation energy
1. Acid hydrolysis of sucrose needs 6.22 kilojoules per mole.
2. With sucrase only 2.15 kilojoules per mole is needed.
3. The enzyme has lowered the activation energy.
