Question 4

What is an enzyme's function?

A. stores genetic information

B. speeds up chemical reactions

C. provides structure

D. provides energy

Question 5

Do chemical reactions occur without enzymes present?

A. No the reaction cannot occur at all

B. Yes the reaction happens but the reaction is slower

Question 6

How do enzymes affect the activation energy (energy needed to start a reaction)

A. lower the activation energy so the reaction happens faster

B. increases the activation energy so the reaction does not occur

C. Does not change the activation energy

Question 7

A. enzymes

B. hormones

C. nucleic acids

D. simple sugars
