Nothing happens

What kind of organic compound is an enzyme?

B. carbohydrate

C. lipid

D. protein

What is the monomer of an enzyme?

A. nucleotides

B. monosaccharides

C. amino acids

D. fatty acids

What is an enzyme's function?

A. stores genetic information

B. speeds up chemical reactions

C. provides structure

D. provides energy

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

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
