This fully-resourced lesson describes the series of reactions in the light- independent stage of photosynthesis. The detailed PowerPoint and accompanying resources have been designed to cover the details of point 5.2.1 (e) of the OCR A-level Biology A specification and detailed planning includes continual links to the previous lesson on the light-dependent stage to ensure that students recognise how the products of that stage, ATP and reduced NADP, are essential for the Calvin cycle
The lesson begins with an existing knowledge check where the students are challenged to recall the names of structures, substances and reactions from the light-dependent stage in order to reveal the abbreviations of the main 3 substances in the light-independent stage. This immediately introduces RuBP, GP and TP and students are then shown how these substances fit into the cycle. The main section of the lesson focuses on the three phases of the Calvin cycle and time is taken to explore the key details of each phase and includes:
- The role of RuBisCO in carbon fixation
- The role of the products of the light-dependent stage, ATP and reduced NADP, in the reduction of GP to TP
- The use of the majority of the TP in the regeneration of RuBP
A step-by-step guide, with discussion points where the class consider selected questions, is used to show how 6 turns of the cycle are needed to form the TP that will then be used to synthesise 1 molecule of glucose. A series of exam-style questions are included at appropriate points of the lesson and this will introduce limiting factors as well as testing their ability to answer questions about this stage when presented with an unfamiliar scientific investigation. The mark schemes are included in the PowerPoint so students can assess their understanding and any misconceptions are immediately addressed.

Module 5.2: Photosynthesis & Respiration (OCR A-level Biology A)
Photosynthesis and respiration are two of the most commonly-assessed topics in the terminal A-level exams but are often poorly understood by students. These 14 lessons have been intricately planned to contain a wide range of activities that will engage and motivate the students whilst covering the key detail to try to deepen their understanding and includes exam-style questions so they are prepared for these assessments. The following specification points in modules 5.2.1 and 5.2.2 of the OCR A-level Biology A course are covered by these lessons: * The structure of a chloroplast and the sites of the two main stages of photosynthesis * The light-dependent stage of photosynthesis * The fixation of carbon dioxide and the light-independent stage of photosynthesis * The uses of triose phosphate * Factors affecting photosynthesis * The need for cellular respiration * The structure of the mitochondrion * The process and site of glycolysis * The link reaction and its site in the cell * The process and site of the Krebs cycle * The importance of coenzymes in cellular respiration * The process and site of oxidative phosphorylation * The chemiosmostic theory * The process of anaerobic respiration in eukaryotes * The relative energy values of carbohydrates, lipids and proteins as respiratory substrates * The use of the respiratory quotient Due to the detail of these lessons, it is estimated that it will take in excess of 2 months of A-level lessons to cover this module If you would like to sample the quality of the lessons, download the uses of triose phosphate, link reaction and respiratory substrates lessons as these have been shared for free

Module 5.2.1: Photosynthesis (OCR A-level Biology A)
This lesson bundle contains 5 fully-resourced lessons which will engage and motivate the students whilst covering the content of module 5.2.1 of the OCR-A-level Biology A specification in the depth of detail required to support them to answer assessment questions on this topic of PHOTOSYNTHESIS confidently. This cellular reaction can be poorly understood by students so intricate planning has gone into the design of the lesson PowerPoints and accompanying resources to ensure that key details are embedded and reinforced throughout and that knowledge acquired in previous lessons is regularly checked. The following specification points are covered by the lessons in this bundle: * The structure of the chloroplasts and the two main stages of photosynthesis * The light-dependent stage of photosynthesis * The fixation of carbon dioxide and the light-independent stage of photosynthesis * The uses of triose phosphate * Factors affecting photosynthesis If you would like to sample the quality of the lessons, then download the "uses of triose phosphate" lesson as this has been shared for free
