Thermoregulation (Edexcel A-level Biology A)

Topic 7: Run for your life (Pearson Edexcel A-level Biology A)

This bundle contains 17 fully-resourced lessons which have been designed to cover the content as detailed in topic 7 (Run for your life) of the Pearson Edexcel A-Level Biology A (Salters Nuffield) specification. The specification points that are covered within these lessons include: * The interaction of muscles, tendons, ligaments and the skeleton in movement * The contraction of skeletal muscle by the sliding filament theory * The overall reaction of aerobic respiration * The enzymes involved in the multi-stepped process of respiration * The roles of glycolysis in aerobic and anaerobic respiration * The role of the link reaction and the Krebs cycle in the complete oxidation of glucose * Understand how ATP is synthesised by oxidative phosphorylation * The fate of lactate after a period of anaerobic respiration * The myogenic nature of cardiac muscle * The coordination of the heart beat * The use of ECGs to aid diagnosis * Calculating cardiac output * The control of heart rate by the medulla oblongata * The control of ventilation rate * The structure of a muscle fibre * The structural and physiological differences between fast and slow twitch muscle fibres * The meaning of negative and positive feedback control * The principle of negative feedback in maintaining systems within narrow limits * The importance of homeostasis to maintain the body in a state of dynamic equilibrium during exercise * DNA transcription factors, including hormones The lessons have been planned so that they contain a wide range of activities and numerous understanding and prior knowledge checks so students can assess their progress against the current topic as well as be challenged to make links to other topics within topic 7 and earlier topics If you would like to see the quality of the lessons, download the link reaction and Krebs cycle, the fate of lactate,the using ECGs and transcription factors lessons as these have been uploaded for free
