| Question | Answer |
| What is aerobic respiration? | It is respiration that involves oxygen. |
| What is the equation for aerobic respiration? | Glucose + Oxygen ↓ Carbon dioxide + Water (+ Energy) |
| How would you test for carbon dioxide? | Breathe into lime water. If it turns from clear to milky, carbon dioxide is present. |
| How would you test for water? | Breathe onto a mirror. If water vapour appears, water is present. |
| Where does respiration occur? | Mitochondria |
| How does respiration occur? | Controlled by enzymes |
| What is anaerobic respiration? | When respiration occurs without enough oxygen. |
| What is the equation for anaerobic respiration in animal cells? | Glucose ↓ Lactic acid + Energy |
| What is the equation for anaerobic respiration in plant and yeast cells? | Glucose ↓ Ethanol + Carbon dioxide |
| What is oxygen debt? | The amount of extra oxygen required after exercise to react the accumulated lactic acids and remove it from the cells. |
| What are the side effects of oxygen debt? | Muscle fatigue and cramp. |
| Define metabolism | All the chemical reactions happening in a living organism. |
| What is the equation for photosynthesis? | Carbon dioxide + Water ↓ Glucose + Oxygen |
| What is chlorophyll and what does it do? | Chlorophyll is the green pigmentation found inside chloroplasts. It is absorbs sunlight for photosynthesis. |
| Define limiting factor | A limiting factor is a part of the photosynthesis reaction that is in short supply which presents the rate of photosynthesis increasing further. |
