Respiration

Question 1

Respiration

Answer 1

chemical reactions in cells that break down nutrient molecules and release energy

Question 2

Aerobic respiration

Answer 2

(involves oxygen, happens in mitochondria)
glucose + oxygen → carbon dioxide + water
C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O

Question 3

Anaerobic respiration

Answer 3

(does not include oxygen, releases less energy)
Glucose → lactic acid + energy
C5H1206 → 2C3H6O3 + ATP

Question 4

Actions to remove lactic acid

Answer 4

1. Aerobic respiration in the liver to break down the lactic acid into carbon dioxide and water
2. a higher heart rate for a time after stopping exercise so that lactic acid can be transported in the blood from the muscles to the liver
3. deeper breathing for a time after stopping exercise to provide the oxygen your liver needs to break down the lactic acid
