Aerobic Respiration (Cambridge O Level Biology)

The diagram below shows an experimental set-up which can be used to investigate gas exchange in a plant leaf.

In which direction would the ink drop move and for what reason?

In an investigation, scientists treated plant roots with a chemical that stops aerobic respiration. They observed that after the treatment, the plant roots absorbed nitrate ions more slowly. 

Which statement explains this observation?

Four metabolic reactions that can occur in living organisms are shown below:

1. C₆H₁₂O₆ + 6O₂ → 6CO₂+ 6H₂O
2. glucose → lactic acid
3. 6CO₂+ 6H₂O → C₆H₁₂O₆ + 6O₂
4. C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂

Which of the above reactions take place in yeast cells to release energy?

Which of the following processes would release the most energy in a cell from one molecule of glucose?

1. Aerobic respiration in yeast
2. Aerobic respiration in animals
3. Aerobic respiration in plants

In which conditions would the cells of a dicotyledonous green plant respire?

Which of the following is the correct balanced symbol equation for aerobic respiration in yeast cells?

The diagram shows the apparatus used to investigate the rate of respiration of germinating pea seeds.

In an experiment, the coloured oil drop moved 24mm to the left in 30 minutes.
Calculate the rate of respiration of the pea seeds in:
mm³ of oxygen, per gram of pea seeds, per minute.
Assume π = 3.0
