LT-F2.2

LT-F2.2 Describe the process of respiration
State :- State three reasons why living cells need energy.
State that cells need oxygen to release energy from food during (aerobic) respiration.
State that carbon dioxide, derived from food, is given off by cells during (aerobic) respiration.
State that heat energy is released during respiration.
Be able to write a word equation for aerobic respiration.
Describe the process of respiration in terms of energy release.
Be able to distinguish between breathing and respiration.
Describe the
route taken by :-
oxygen from the lungs to respiring tissue in humans.
glucose from the small intestine to respiring tissue in humans.
Describe the difference between inhaled and exhaled air in terms of: oxygen content carbon dioxide content, temperature, moisture.

 

1 Demonstrate the release of heat energy , carbon dioxide and water from sucrose by burning in oxygen.
2 Discuss the need of living cells for food and oxygen and the need to remove waste carbon dioxide.
4 Discuss the distinction between respiration and breathing.
5 Use torso and other models, CD Roms and other A/V materials to investigate the route taken by oxygen from the lungs to a leg muscle cell and the route taken by glucose from the stomach to a leg muscle cell.
6 Investigate the differences between inhaled and exhaled air, i.e. oxygen concentration, temperature, moisture and carbon dioxide concentration.
7 Plan and carry out simple investigations to show energy release and uptake of oxygen in respiring seeds or invertebrates.
