1

What is aerobic respiration?

Aerobic respiration uses oxygen to release energy.

2

What is the word equation for aerobic respiration?

glucose + oxygen = carbon dioxide + water

3

What is the balanced symbol equation for respiration?

c6h12o6 + 6o2 = 6co2 + 6h20 + energy

4

What is the formula for RQ?

RQ = carbon dioxide produced/oxygen used

5

Where is energy stored?

ATP molecules.

6

What is metabolic rate?

Metabolic rate is the amount of energy your body needs.

7

Which waste gas do you need to breathe out?

Carbon dioxide.

8

What is anaerobic respiration?

Anaerobic respiration is the release of energy without the use of oxygen and produces lactic acid as waste.

9

What happens after a sprint?

- heart continues to beat faster than normal so blood can carry lactic acid away from muscles to be broken down
- breathing remains heavy for a few minutes to obtain extra oxygen
- panting to replace oxygen

10

What is oxygen debt?

A temporary oxygen shortage in the body tissues arising from exercise.
