Answer 12

A chemical reaction which results in the breaking of bonds, and the gaining if water.

Question 13

What does the polysaccharide of starch look like?

Answer 13

Glucose molecules bonded to form a chain

Question 14

What does the polysaccharide glycogen look like?

Answer 14

Glucose molecules bonded together, and stacked in top of each other

Question 15

What is the primary function of lipids?

Answer 15

They store energy for long term use, form cell membranes, and are responsible for cell communication and bone structure.

Question 16

What elements create lipids?

Answer 16

Hydrogen
Carbon
Oxygen

Question 17

What are lipids composed of?

Answer 17

3 fatty acids and glycerol

Hence the term triglycerides

Question 18

What is the difference between saturated and unsaturated fats?

Answer 18

Unsaturated fats have a double bond in the fatty acid chain. Unsaturated fats are solid at room temperature, while saturated fats are liquid.

Question 19

Why would a polysaccharide have more energy than a monosaccharide or disaccharide?

Answer 19

Energy is stored in bonds, and there are more bonds within a polysaccharide.

Question 20

How do you tell the difference between carbohydrates and lipids when looking at their chemical structure? Seeing as how they are both composed of the same elements: carbon, hydrogen, and oxygen.

Answer 20

Carbohydrates follow closely a 1:2:1 ratio. (C:H:O)
