This fully-resourced lesson describes how GALP is used as a raw material in the production of monosaccharides, amino acids and other molecules. The engaging and detailed PowerPoint and accompanying resources have been primarily designed to cover point 5.7 (vii) of the Edexcel A-level Biology B specification concerning the uses of GALP but as the lesson makes continual references to biological molecules, it can act as a revision tool for a lot of the content of topic 1.
The previous lesson covered the light-independent stage and this lesson builds on that understanding to demonstrate how the product of the Calvin cycle, glyceraldehyde phosphate, is used. The start of the lesson challenges the students to identify two errors in a diagram of the cycle so that they can recall that most of the GALP molecules are used in the regeneration of ribulose bisphosphate. A quiz version of Pointless runs throughout the lesson and this is used to challenge the students to recall a biological molecule from its description. Once each molecule has been revealed, time is taken to go through the details of the formation and synthesis of this molecule from GALP or from GP in the case of fatty and amino acids. The following molecules are considered in detail during this lesson:
- glucose (and fructose and galactose)
- sucrose
- starch and cellulose
- glycerol and fatty acids
- amino acids
- nucleic acids
A range of activities are used to challenge their prior knowledge of these molecules and mark schemes are always displayed for the exam-style questions to allow the students to assess their understanding.
As detailed above, this lesson has been specifically written to tie in with the earlier lessons in this module on the structure of the chloroplast and the light-dependent and light-independent stages of photosynthesis.

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 If you would like to sample the quality of the lessons, download the link reaction, Krebs cycle and light-independent stage lessons as these have been shared for free

Topic 5.7: Photosynthesis (Edexcel A-level Biology B)
This bundle contains 5 fully-resourced and highly-detailed lessons which build on the students knowledge of photosynthesis from GCSE and add the fine detail that is critical when tackling questions on this topic in the A-level exams. The lesson PowerPoints and accompanying resources are filled with a wide range of activities that will engage, motivate and challenge the students whilst the detail of the following specification points in topic 5.7 of the Edexcel A-level Biology B course are covered: * The structure of the chloroplast * The role of the thylakoid membranes in the light-dependent stage of photosynthesis * The processes of cyclic and non-cyclic photophosphorylation * The role of the stroma in the light-independent stage * The fixation of carbon dioxide * The use of ATP and reduced NADP from the light-dependent stage in the Calvin cycle * The use of GALP as a raw material * The factors that limit photosynthesis If you would like to sample the quality of these lessons, then download the light-independent stage lesson as this has been shared for free
