What happens to the active site of an enzyme when a substrate binds to it?

• It becomes permanently altered

• It can change shape slightly

• It remains unchanged

• It loses its function

What is the primary role of enzymes in biological reactions?

• To slow down chemical reactions

• To provide structural support to cells

• To act as catalysts and speed up reactions

• To store genetic information

The enzymes names end in -ase, but also are created so you know what they break down or produce. Match the following enzyme with the appropriate job it does.

Groups:

(a) lactase

,

(b) lipases

,

(c) proteases

,

(d) dehydrogenases

• group of enzymes that hydrolyze peptide bonds in proteins.

• This group of enzymes help digest fats in the gut.

• removes hydrogens from molecules.

• This enzyme breaks down lactose from milk into galactose and glucose.

What are cofactors and coenzymes?

• Types of enzymes

• Substrates for enzymes

• Helpers for enzymes

• Products of enzyme reactions

What happens to an enzyme when its shape becomes distorted due to non-ideal environmental conditions like extreme pH or temperature?

• It becomes more efficient

• It denatures

• It changes its substrate

• It forms new bonds

Does this make sense?

• YES

• NO
