Enzymes In Biochemical Reactions — Role & Importance

Sample 3 < Sample 1 < Sample 2, because reactions occur faster at higher heat.

Sample 1 < Sample 3 ~ Sample 2, because slight change in temperature causes mixing of solutes and increases reaction rate.

Sample 3 ~ Sample 2 < Sample 1, because changing temperature can change the shape of the activation site of an enzyme, causing it to be unable to react with its substrate.

Sample 3 < Sample 2 ~ Sample 1, because cooling an enzyme causes it to lose its ability to catalyze reactions
