**Checklist for iGCSE Biology: Respiration and gas exchange** **Topic**  I have asked for help -------------------------------------------------------------------------------------------------------------------------------------------- -- ----------------------- -- ----------------------- Understand that respiration produces **ATP** from glucose in all living organisms Know that ATP is what cells use for an energy supply Define **aerobic respiration** Know the word and balanced chemical equation for aerobic respiration Define **anaerobic respiration** State the difference between aerobic and anaerobic respiration Know the word and balanced chemical equation for anaerobic respiration in human cells Know the word and balanced chemical equation for anaerobic respiration in yeast cells Understand that **bread and alcohol** are made using anaerobic respiration by yeast Explain that **yoghur**t is made by ***Lactobacillus* bacteria** doing anaerobic respiration and using lactose sugar Describe and interpret the experiment that shows heat is released by living organisms when they respire Understand the role of **diffusion** in gas exchange Understand gas exchange in plants (e.g. at the leaf) Understand gas exchange in the human **alveolus** Understand that in plants respiration is continuous day and might but photosynthesis only happens in the day. Label the human thorax -- **trachea, bronchus (i), bronchioles, alveolus (alveoli), ribs, intercostal muscles, diaphragm** Understand the role of the **ribs** and **intercostal muscles** in **ventilation** (breathing in and out) Define **inhale and exhale** Explain how **alveoli** are adapted for gas exchange Explain the effect of **carbon monoxide, nicotine** and **tar** from smoking. Understand the effects of **smoking** on human health (**lung cancer**, effects on the circulatory system e.g. **coronary heart disease**) Describe and interpret the results of practicals that look at the effect of exercise on breathing rate. Essential scientific **vocabulary is in bold**. Make sure you know what each word means.
