K. Factors That Affect Enzyme Activity

Question 0

pH

Answer 0

Denatures enzyme if too low or high

Question 1

Temperature

Answer 1

Denatures enzyme if too high

Slows down enzyme if too low

Question 2

Cofactors

Answer 2

Small, inorganic, usually metal ion

Question 3

Coenzyme

Answer 3

Small, organic
Ex. Vitamins
Ex. N.A.D, F.A.D

Question 4

Inhibitors

Answer 4

Decrease the enzymes function

Question 5

Inhibitors:

Competitive inhibition

Answer 5

Attach to active site

Out competes the normal substrates for entrance

Question 6

Inhibitors:

Non competitive inhibition

Answer 6

Bond to non active site location

Decrease enzyme activity because of changing its shape (denature)

Question 7

Limiting factors

Answer 7

The factor (substance) in shortest supply will determine the rate of he reaction.

Question 8

Limiting factors:

Enzyme concentration

Answer 8

Low amounts of enzyme concentration can limit the rate of the reaction

Question 9

Limiting factors:

Substrate concentration

Answer 9

Low amounts of substrate concentration can limit the reaction

Question 10

Limiting factors:

Saturation

Answer 10

Too busy

Question 11

What are the factors that affect enzyme activity

Answer 11

1. Temperature
2. pH
3. Cofactors
4. Coenzymes
5. Inhibitors
6. Limiting factors
