proteins

Question 1

What type of protein is an enzyme

Answer 1

globular protein

Question 2

What is a globular protein

Answer 2

a class of spherical-shaped proteins that are generally water-soluble and have metabolic roles

Question 3

what is an intracellular enzyme

Answer 3

an enzyme that works within cells

Question 4

what is an extracellular enzyme

Answer 4

an enzyme that works outside of cells

Question 5

State what is meant by the induced fit model.

Answer 5

Active site changes shape

to become complementary to the substrate

Question 6

Explain how the structure of an enzyme is related to its function.

Answer 6

An enzyme has a specific tertiary structure

forms a specific active site complementary to the substrate

This allows the enzyme-substrate complex to be formed

Question 7

Explain the effect of high temperature on enzyme activity.

Answer 7

high temperature increases kinetic energy, initially increases rate

after a while high temperature breaks ionic bonds and hydrogen bonds

This alters tertiary structure and changes shape of active site

substrate no longer binds

Question 8

What is denaturation

Answer 8

a change in tertiary structure that causes change in shape of the active site of
