Question 2

What are the four levels of protein structure?

Answer 2

Primary, secondary, tertiary, and quaternary

Question 3

Define what an enzyme is

Answer 3

Enzymes are proteins which act as biological catalysts and speed up the rate of reaction by lowering the activation energy. Every enzyme will only react with a specific molecule called a substrate which binds to a region of the enzyme called the active site.

Question 4

How does a competitive inhibitor work?

Answer 4

A competitive inhibitor binds with the active site of an enzyme, forming an enzyme-inhibitor complex, and resulting in the substrate being unable to bond with the enzyme.

Question 5

what is a zwitterion?

Answer 5

A zwitterion is an ion that contains two functional groups. In simple terms, it is an ion possessing both positive and negative electrical charges.
