The blueprint

Question 1

Describe how a non-competitive inhibitor can reduce rate of reaction (3)

Answer 1

1. attaches to enzyme at site other than the active site
2. changes the shape of the active site
3. active site and substrate no longer complementary

Question 2

The scientist concluded pectin is a non-competitive inhibitor of lipase. Explain why the scientist concluded this.

Answer 2

Increasing the amount of substrate does not increase rate of reaction

Question 3

calculate max length of the large lipid droplets

Answer 3

I = 4mm =4000 um
m = 500
4000/500 = 8 = max length
8 -> 25% = (+-) 2um

Question 4

no lipid droplets are visible with the optical microscope. explain why

Answer 4

They cannot be seen as the resolution of the microscope is low, and due to emulsification taking place.

Question 5

complete table 1 with plants, algae, fungi, prokaryotes

Answer 5

cellulose: plants +algae
murein: prokaryotes
chitin: fungi
