Enzymes

Question 1

What is induced fit?

Answer 1

When a substrate binds to the active site and the active site wraps around the substrate. This increases the rate of reaction

Question 2

What do enzymes do to the activation energy?

Answer 2

Lower it

Question 3

How is the active site of the enzyme linked to a lower activation energy?

Answer 3

It holds the substrates into the correct position for a reaction to take place

Question 4

What allows a reaction to take place at a lower temperature?

Answer 4

Enzymes provide an alternative metabolic pathway for reactions, allowing a reduced Ea

Question 5

What is competitive inhibition?

Answer 5

When the inhibitor molecule competes for the active site by binding to it. It will have a similar structure to the enzyme substrate and interfere with the active site, so the substrate cannot bind

Question 6

What is non-competitive inhibition?

Answer 6

When the inhibitor molecule binds to another part of the enzyme. This alters the shape of the enzyme and the active site, so the substrate can no longer fit

Question 7

What is feedback inhibition?

Answer 7

When a product lowers the activity of an enzyme in its synthesis path
