| What do muscle cells need more of during exercise? | Energy |
| What are the two waste products of aerobic respiration? | Carbon dioxide and water |
| Which substance is stored in the muscles and can be converted into glucose? | Glycogen |
| What is the word equation for aerobic respiration? | Glucose + Oxygen -> Carbon dioxide +Water (+energy) |
| Why do muscles become fatigued (tired) during vigorous exercise? | Lactic acid builds up in the muscles |
| What changes occur to the breathing and heart rate during exercise? | The breathing rate and heart rate increase |
| Why do blood vessels in the muscles dilate during exercise? | This allows an increased blood supply to the muscle cells to provide oxygen and glucose more quickly and to remove carbon dioxide faster |
