Enzyme Inhibitors

Question 1

What is the role of an Inhibitor

Answer 1

It slows down the rate of enzyme activity

Question 2

What is a competitive inhibitor

Answer 2

A competitive inhibitor competes with the substrate for the active site, when it enters the active site is physically blocks the substrate from entering,

They are similar shape to the substrate, normally reversible, and can be overcome by increasing substrate concentration

Question 3

What is a Non-competitive inhibitor

Answer 3

This is a type of inhibitor that doesn’t bind to the enzyme’s active site, however it binds elsewhere and causes conformational changes to the enzyme, this means that the substrate is unable to fit.

Mostly Non-reversible

Question 4

Advantages of using enzymes rather than inorganic catalysts

Answer 4

They are specific
Work at normal temperature and pressure (much less energy needed)
Efficent

Question 5

What are some industrial uses for enzymes?

Answer 5

Baby food, Detergent, Dye, Apple juice, food processing (amylase for bread, protease for cheese), textiles (cellulase for treating demon to create stone wash), Grain processing (conversion of corn starch into high fructose syrup)

Question 6

How are most Enzymes grown

Answer 6

From one micro-organism, in bulk (this is due to the high growth rates)
