This fully-resourced lesson describes how carbon dioxide, light intensity and temperature limit the rate of photosynthesis. The PowerPoint and accompanying resources have been designed to cover point 5.7 (viii) of the Edexcel A-level Biology B specification
The lesson has been specifically written to tie in with the four previous lessons in this topic which covered the structure of the chloroplast, the light-dependent and light-independent stages and GALP as a raw material. Exam-style questions are included throughout the lesson and these require the students to explain why light intensity is important for both reactions as well as challenging them on their ability to describe how the relative concentrations of GP, GALP and RuBP would change as carbon dioxide concentration decreases. There are also links to previous topics such as enzymes when they are asked to explain why an increase in temperature above the optimum will limit the rate of photosynthesis. Step by step guides are included to support them to form some of the answers and mark schemes are always displayed so that they can quickly assess their understanding and address any misconceptions

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
