• slow down chemical reactions

• do nothing to a chemical reaction

Without proper enzyme regulation you would die

• true

• false

How does an enzymes shape relate to its function?

• the shape of the enzyme has no relation to its function

• the enzyme is shaped specially for certain substrates to perform a specific reaction

• the enzyme shape acts as a receptor to certain products

• the enzyme shape can fit into specific substrates to cease a reaction

A is the

• substrate

• enzyme-substrate complex

• products

B is the

• substrate

• enzyme-substrate complex

• products

C is the

• substrate

• enzyme-substrate complex

• products

What can affect enzyme ability? (select all that apply)

• pH

• enzyme potential

What are some of the impacts you would expect to observe to the internal health of the cells of someone with a lysosomal disorder?

• inability to destroy engulfed bacteria

• inability to digest food supply

• inability to digest cellular waste

• inability to construct glycogen

An enzyme ________ the activation energy needed for a reaction to occur.

• decreases

• increases

• does nothing to

• increases then decreases
