This lesson describes the light-dependent stage of photosynthesis and focuses on the mechanisms involved in the production of ATP and reduced NADP. The detailed PowerPoint and accompanying resources have been designed to cover the details of point 5.2.1 (d) of the OCR A-level Biology A specification and has been specifically planned to link with the previous lesson on the structure of the chloroplast and photosynthesis and to prepare the students for the next lesson on the light-independent stage.
The light-dependent stage is a process which students can find difficult to understand in the necessary detail so this lesson has been planned to walk them through all of the key details. Time is taken to describe the roles of the major protein complexes that are embedded in the thylakoid membrane and this includes the two photosystems, the cytochrome proton pump and ATP synthase. A series of exam-style questions have been written that link to other biological topics in this course such as eukaryotic cell structures and membrane transport as well as application questions to challenge them to apply their understanding. Some of these resources have been differentiated to allow students of differing abilities to access the work and to be pushed at the same time. Students will learn that there are two pathways that the electron can take from PSI and at the completion of the two tasks which describe each of these pathways, they will understand how ATP is generated in non-cyclic and cyclic photophosphorylation. The final task of the lesson asks them to compare these two forms of photophosphorylation to check that they understand when photolysis is involved and reduced NADP is formed.
Due to the detail included in this lesson, it is estimated that it will take in excess of 2.5 hours of allocated A-level teaching time to complete.

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 16 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 importance of the photosynthetic pigments * Using thin-layer chromatography to separate photosynthetic pigments * 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 7 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 importance of photosynthetic pigments for photosynthesis * Using thin-layer chromatography to separate photosynthetic pigments * 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
