Enzymes

Question 1

What are proteins broken down by?

Answer 1

Proteases found in the stomach, pancreas and small intestine.

Question 2

Explian the role of an active site of an enzyme?

Answer 2

To bind to a substrate for reaction to take place.

Question 3

Describe what effect a mutation could have on the action of an enzyme?

Answer 3

Change in shape of active site
Prevents binding to substrate
Enzyme can no longer function

Question 4

Decribe how named factors affect the rate of an enzyme?

Answer 4

Temperature too low - not enough energy for a reaction
Over 37 c changes enzyme shape
Temperature too high - enzyme is denatured

Optimum pH around 6 to 8
pH to high or low - enzyme becomes denatured

Higher concentration means faster reactions due to more collisions.
