Biomolecule Basics

Question 1

Proteins

Answer 1

Provide structural support and act as catalysts that facilitate chemical reactions

Question 2

Nucleic Acids

Answer 2

Encode and transmit genetic information

Question 3

Carbohydrates

Answer 3

Provide source of energy and make up the cell wall in bacteria, plants, and algae

Question 4

Lipids

Answer 4

Make up cell membranes. store energy, and act as signaling molecules

Question 5

Polymers

Answer 5

Molecules made up of repeated monomers, connected by covalent bonds

Question 6

Match the polymers to their monomers

Answer 6

Proteins - Amino Acids
Nucleic Acids - Nucleotides
Carbohydrates - Simple sugars (glucose, fructose, etc.)
Lipids - Fatty Acids bonded to other organic molecules

Question 7

Dehydration Synthesis (Condensation Reaction)

Answer 7

Removes a water molecule, forming a new bond. When the water molecule is released, a polymer is built

Question 8

Hydrolysis Reaction

Answer 8

Adds a water molecule, breaking a bond. When the water molecule is added, a polymer is broken down
