What are enzymes made from?

What is a catalyst?

What is an enzyme substrate?

What is an enzyme active site? What does it do?

Label the active site.

Label the substarte.

What do we call it when the shape of an enzymes active site changes so that it no longer fits the substrate?

Label the product of the enzyme reaction and use it to explain what a product is.

What is the name given to the theory (hypothesis) explaining how an enzyme works shown in the diagram?

List the 3 factors that affect the rate of an enzyme controlled reaction.
