Chapter 1 - Water And Carbohydrates

Question 1

Monomers

Answer 1

A single molecule that can be bound with the same or similar molecules

Question 2

Polymer

Answer 2

When the same or similar monomers bind together to form polymers

Question 3

Dimer

Answer 3

Two monomers bonded together, forms water

Question 4

Condensation reaction

Answer 4

When monomers bind to other monomers, and a H from one monomer and a OH from the other monomer is removed to produce water and a polymer
