Edexcel A-Level Biology Topic 1 REVISION (Lifestyle, Health and Risk)

This is a fully-resourced REVISION lesson that consists of an engaging PowerPoint (87 slides) and associated worksheets that challenge the students on their knowledge of the content of Topic 1 (Lifestyle, Health and Risk) of the Edexcel A-Level Biology A (Salters-Nuffield) specification. A wide range of activities have been written into the lesson to maintain motivation and these tasks include exam questions (with answers), understanding checks, differentiated tasks and quiz competitions.

The lesson has been designed to include as much which of the content from topic 1, but the following specification points have been given particular attention:

  • The differences between monosaccharides, disaccharides and polysaccharides, including glycogen and starch (amylose and amylopectin).
  • Be able to relate the structures of monosaccharides, disaccharides and polysaccharides to their roles in providing and storing energy
  • Know how monosaccharides join to form disaccharides (sucrose, lactose and maltose) and polysaccharides (glycogen and amylose) through condensation reactions forming glycosidic bonds, and how these can be split through hydrolysis reactions.
  • Know how a triglyceride is synthesised by the formation of ester bonds during condensation reactions between glycerol and three fatty acids.
  • Understand the course of events that leads to atherosclerosis
  • Know how factors such as genetics, diet, age, gender, high blood pressure, smoking and inactivity increase the risk of cardiovascular disease
  • Know the benefits and risks of treatments for CVD
  • Understand the blood-clotting process and its role in CVD
  • Understand how the structures of arteries and veins) relate to their functions.
  • Understand the importance of water as a solvent in transport, including its dipole nature.

This lesson can be used at numerous points over the duration of the course, as an end of topic revision aid, in the lead up to the mocks or in the lead up to the actual A-level exams.
