Enzymes Quiz

What is the function of enzymes?

• To break down or make substrates

• To regulate body processes

• To produce lactase

• To bind to active sites

Answer explanation

What is the specific area in an enzyme where substrates bind?

• Active site

• Induced fit

• Product

• Catalyst

What happens when substrates bind to an enzyme?

• The product is formed

• The enzyme gets used up

• The enzyme becomes denatured

• The active site changes shape

Chemical reactions require enzymes to

• make lactose

• make reactions go faster

• use up more energy

• change shape
