This fully-resourced lesson describes how light intensity, carbon dioxide concentration and temperature limit the rate of photosynthesis. The PowerPoint and accompanying resources have been designed to cover point 5.2.1 (g) (i) of the OCR A-level Biology A specification and also includes a brief consideration of water stress.
The lesson has been specifically written to tie in with the three previous lessons in this module which covered the structure of the chloroplast, the light-dependent and light-independent stages and the uses of TP. 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, TP 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.

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
