Which best describes how the shape of an enzyme affects its function?

• It determines the specific reaction it will catalyze.

• It determines the raw products needed for the reaction.

• It determines whether a reaction will be slowed or sped up.

• It determines the products that will result from the reaction.

Which role do enzymes play in cells?

• They are biosubstrates that speed up chemical reactions.

• They are biosubstrates that decrease chemical reactions.

• They are biocatalysts that decrease the activation energy in chemical reactions.

• They are biocatalysts that increase and decrease the activation

  energy in chemical reactions.
