Biology Cambridge IGCSE Course – Code 0610 and 0970: Topic 12 – Respiration
Course Description:
Welcome to our Biology Cambridge IGCSE course, meticulously tailored to help you conquer the intricacies of Topic 12: Respiration. This comprehensive course is specifically designed for both Code 0610 and Code 0970 syllabi, ensuring you’re well-prepared for the IGCSE Biology examination.
Course Highlights:
- Comprehensive Core and Supplement Objectives: Master all core and supplement objectives as outlined in the syllabus for theory (papers 1, 2, 3, 4). These objectives provide a solid foundation for exam success.
- Thoroughly Explained Experiments: Gain a deep understanding of practical experiments with detailed explanations. Notes summarize the method, results, interpretation, evaluation, reliability, and conclusion, enabling you to excel in paper 6 questions.
Course Outline & Objectives (Core and Supplement):
- Respiration (Lesson 1): Key objectives include:
- State the uses of energy in living organisms, including muscle contraction, protein synthesis, cell division, active transport, growth, the passage of nerve impulses and the maintenance of a constant body temperature.
- Aerobic Respiration- Oxygen in expired air (Lesson 2): Key objectives include:
- Describe aerobic respiration as the chemical reactions in cells that use oxygen to break down nutrient molecules to release energy.
- State the word equation for aerobic respiration as: glucose + oxygen → carbon dioxide + water.
- State the balanced chemical equation for aerobic respiration as: C6H12O6 + 6O2 → 6CO2 + 6H2O.
- Anaerobic Respiration (Lesson 3): Key objectives include:
- Describe anaerobic respiration as the chemical reactions in cells that break down nutrient molecules to release energy without using oxygen.
- State that anaerobic respiration releases much less energy per glucose molecule than aerobic respiration.
- State the word equation for anaerobic respiration in yeast as glucose → alcohol + carbon dioxide.
- State the word equation for anaerobic respiration in muscles during vigorous exercise as glucose → lactic acid.
- State the balanced chemical equation for anaerobic respiration in yeast as C6H12O6 → 2C2H5OH + 2CO2.
- State that lactic acid builds up in muscles and blood during vigorous exercise causing an oxygen debt.
- Outline how the oxygen debt is removed after exercise, limited to (a) continuation of fast heart rate to transport lactic acid in the blood from the muscles to the liver (b) continuation of deeper and faster breathing to supply oxygen for aerobic respiration of lactic acid (c) aerobic respiration of lactic acid in the liver.
- Experiment – The Effect of Temperature on Yeast Respiration (Lesson 4): Key objectives include:
- To investigate the effect of temperature on respiration in yeast.
- Experiment – Using Up Oxygen During Respiration (Lesson 5): Key objectives include:
- To investigate using up oxygen during respiration.
