Answer 3

Hydrogen Bonds

Question 4

Carbohydrate

Answer 4

• Polar
• Soluble in water
• hydrophilic

Question 5

Hydrocarbon

Answer 5

• Not soluble in water
• Amphipathic

Question 6

Explain the structure of the phospholipid bilayer and why it is structured like so

Answer 6

The phospholipid bilayers are responsible for the formation of biological membranes.

Hydrophilic is the head, facing outward towards water and hydrophobic is the tail, facing in towards each other

Question 7

Answer 7

Energy
Reproduction
Cells
Information
Evolution

Question 8

What connects amino acids and enzymes

Answer 8

Amino acids make a protein and proteins make up enzymes

Question 9

What connects potential energy with ionic bonds

Answer 9

Potential energy is in ionic bonds and when you break them energy is released

Question 10

What does it mean to be amphipathic

Answer 10

To have both hydrophobic and hydrophilic properties

Question 11

Why can’t humans digest cellulose even though it is also a sugar/carbohydrate?

Answer 11
