(FREE) L1 - Aerobic & Anaerobic Respiration - 2.34 to 2.36

2.34 to 2.39, 2.46 to 2.50 - Respiration & Gas Exchange (IGCSE Biology Edexcel 9-1)

**IGCSE Biology 9-1** 2.34 understand how the process of respiration produces ATP in living organisms 2.35 know that ATP provides energy for cells 2.36 describe the differences between aerobic and anaerobic respiration 2.37 know the word equation and the balanced chemical symbol equation for aerobic respiration in living organisms 2.38 know the word equation for anaerobic respiration in plants and in animals 2.39 practical: investigate the evolution of carbon dioxide and heat from respiring seeds or other suitable living organisms 2.46 describe the structure of the thorax, including the ribs, intercostal muscles, diaphragm, trachea, bronchi, bronchioles, alveoli and pleural membranes 2.47 understand the role of the intercostal muscles and the diaphragm in ventilation 2.48 explain how alveoli are adapted for gas exchange by diffusion between air in the lungs and blood in capillaries 2.49 understand the biological consequences of smoking in relation to the lungs and the circulatory system, including coronary heart disease 2.50 practical: investigate breathing in humans, including the release of carbon dioxide and the effect of exercise Series of lessons on respiration and gas exchange, including practical lab work and lots of practice on past paper sections on respiration and the respiratory system. **Any and all feedback appreciated**
