3.1.1 Monomers and Polymers (Unit 1 Biological Molecules)

Question 1

What is a condensation reaction?

Answer 1

Monomers are joined together producing a larger molecule forming a bond.

A molecule of water is formed in this process

What is a hydrolysis reaction?

Answer 2

Polymers and dimers are split a part breaking bonds

A water molecule is formed in this process
