Topic 1: Molecules, Transport & Health (Edexcel International A-level Biology)

This bundle contains 11 detailed lesson PowerPoints and the variety of tasks that are contained within these slides and the accompanying resources will engage and motivate the students whilst covering the following specification points within topic 1 of the Edexcel International A-level Biology specification:

• The importance of water as a solvent in transport
• The difference between monosaccharides, disaccharides and polysaccharides
• The relationship between the structure and function of monosaccharides
• The formation and breakdown of disaccharides
• The relationship between the structure and function of glycogen, amylose and amylopectin
• The synthesis of triglycerides
• The differences between saturated and unsaturated lipids
• The relationship between the structure of capillaries, arteries and veins and their functions
• Atrial systole, ventricular systole and cardiac diastole as the three stages of the cardiac cycle
• The operation of the mammalian heart and the major blood vessels
• The role of haemoglobin in the transport of oxygen and carbon dioxide
• The oxygen dissociation curve for foetal haemoglobin and during the Bohr effect
• The course of events that lead to atherosclerosis
• The blood clotting process
