Enzymes

Question 1

What are Enzymes

Answer 1

Enzymes are globular proteins that function as a biological catalyst

Question 2

Denatured Enzymes

Answer 2

Enzymes that have lost their 3D shape/structure, causing them to lose their function.

Caused by unfavorable conditions (e.g. high temp, low pH, etc)

Question 3

Active Sites

Answer 3

Active sites are the sites on the surface of an enzyme to which substrates combine.

Only specific substrates will fit into an enzymes active site (lock and key)

Question 4

Factors that affect enzyme activity

Answer 4

Temperature
pH
Substrate concentration
Enzyme concentration
Presence of Inhibitors

Question 5

Competitive Inhibitor

Answer 5

Competitive inhibitors bind to the active site of an enzyme, which prevents the correct substrates from binding.

Adding more substrates will reduce the effect of the inhibitor.

Question 6

Non-Competitive Inhibitors

Answer 6

Non-competitive inhibitors bind to an enzyme but isn’t in the active site.

Adding more substrates will have no effect of the reaction rate.

Question 7

Enzyme Inhibitors

Answer 7

Is a molecule that binds to an enzyme and blocks it’s activity.

Question 8

Substrate

Answer 8

A molecule that an enzyme reacts with.
Binds with the active site.
