Topic 5: Energy for biological processes (Edexcel A-level Biology B)

Respiration and photosynthesis are two of the most important biological processes, which can be poorly understood by students but unsurprisingly are commonly assessed in the terminal exams. These 11 lessons have been intricately planned so that they contain a wide range of activities that will engage the students whilst covering the key detail to try to deepen their understanding and include exam-style questions so they are prepared for the assessments.

The following specification points in topic 5 of the Edexcel A-level Biology B course are covered by these 11 fully-resourced lessons:

• Cellular respiration yields ATP
• The different stages of aerobic respiration
• The conversion of glucose to pyruvate during glycolysis
• The mitochondrial matrix as the site of the Link reaction and Krebs cycle
• The production of carbon dioxide, reduced NAD and ATP in the Krebs cycle
• Oxidative phosphorylation
• The yield of ATP from anaerobic respiration
• The production of lactate in mammalian muscles
• Ethanol formation in plants
• The meaning of the absorption and action spectra
• The reason for a variety of photosynthetic pigments in plants
• The structure of the chloroplasts
• The role of thylakoid membranes in the light-dependent stage
• The process of cyclic and non-cyclic photophosphorylation
• The use of reduced NADP and ATP in the Calvin cycle
• Understand how GALP is used as a raw material in the production of monosaccharides, amino acids and other molecules
• Factors that limit photosynthesis including carbon dioxide, light intensity and temperature

Due to the detail of these lessons, it is estimated that it will take in excess of a month of A-level lessons to cover these lessons
