e) True
f) False
3.
a) Overall energy released during reaction: Both curves (with and without enzyme) end at the same point on the y-axis, indicating the same net energy change.
b) Activation energy with enzyme: The red curve shows a lower peak, meaning less energy is needed to start the reaction.
c) Activation energy without enzyme: The blue curve has a higher peak, indicating more energy is required to initiate the reaction.
Parent Tip: Review the logic above to help your child master the concept of enzymes worksheet.
