Which of the following is a direct use of energy released during respiration in living organisms?

Question 5

1 mark

What is the correct balanced chemical equation for aerobic respiration?

Question 6

2 marks

List two essential uses of the energy released during respiration in living organisms.

Write your answer out first, then check it against the worked solution.

Question 7

3 marks

Identify three specific physiological processes in the human body that require the energy released from the chemical reactions of respiration.

Write your answer out first, then check it against the worked solution.

Question 8

5 marks

A root hair cell requires a high rate of respiration to absorb mineral ions from the soil. Explain the relationship between the concentration of mitochondria in these cells and the rate of mineral uptake.

Write your answer out first, then check it against the worked solution.

Question 9

5 marks

Compare and contrast aerobic and anaerobic respiration in terms of oxygen requirement, energy release, and products. Explain why human muscles may resort to anaerobic respiration during strenuous exercise despite its lower energy yield.

Write your answer out first, then check it against the worked solution.

Question 10

6 marks

(a) List four ways in which the energy released during respiration is used by a human body.

(b) Some of the energy released in respiration is used for active transport. Explain the importance of this process for a plant, specifically focusing on the uptake of mineral ions from the soil.

(c) Identify the specific cell organelle where most of the aerobic respiration reactions occur and explain why this organelle is often referred to as the 'powerhouse' of the cell.

Write your answer out first, then check it against the worked solution.
