This fully-resourced lesson challenges students to identify environmental factors that limit the rate of photosynthesis. The PowerPoint and accompanying resources have been designed to cover the fourth part of point 5.1 of the AQA A-level Biology specification and focuses on light intensity, carbon dioxide concentration and temperature.
The lesson has been specifically written to tie in with the three previous lessons in this topic which covered the structure of the chloroplast, the light-dependent reactions and the light-independent reactions. 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.

Topic 5.1: Photosynthesis (AQA A-level Biology)
This bundle of detailed lesson PowerPoints and accompanying resources have been designed to cover the content of topic 5.1 (Photosynthesis) in the AQA A-level Biology specification. This cellular reaction can prove difficult for the students to understand, so extra planning has gone into these 4 lessons to ensure that the key details of the reactions are embedded and understanding is constantly checked through a variety of activities. All of the exam-style questions which are used in these current understanding and prior knowledge checks have mark schemes that are included in the PowerPoint to allow the students to assess their work. If you would like to sample the quality of these lessons, download the chloroplast structure lesson as this has been uploaded for free.

Topics 5.1 & 5.2: Respiration & photosynthesis (AQA A-level Biology)
Respiration and photosynthesis are two of the most commonly-assessed topics in the terminal A-level exams but can be the least well understood by students. These 11 lessons have been intricately planned to 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 these assessments. The following specification points in topics 5.1 and 5.2 of the AQA A-level Biology course are covered by these lessons: * The photoionisation of chlorophyll * The production of ATP and reduced NADP through the transfer of electrons and pumping of protons across the thylakoid membrane * Photolysis of water to produce protons, electrons and oxygen * The use of the products of the light-dependent reaction in the Calvin cycle * Carbon fixation involving RUBISCO * The reduction of GP to TP * The regeneration of RuBP from TP * The conversion of TP to organic substances * The environmental factors that limit the rate of photosynthesis * Respiration produces ATP * Glycolysis as the first stage of aerobic and anaerobic respiration * The conversion of pyruvate to ethanol or lactate using reduced NAD * The key details of the Link reaction, Krebs cycle and oxidative phosphorylation * The metabolic pathways of other respiratory substrates 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 specification points If you would like to sample the quality of the lessons, download the chloroplast structure, anaerobic respiration and oxidative phosphorylation lessons as these have been shared for free

Topic 5: Energy transfers in and between organisms (AQA A-level Biology)
Normally the first topic to be taught in the second year of the AQA A-level Biology course, topic 5 contains some very important biological processes which include photosynthesis, respiration and energy transfer between organisms. All 17 lessons included in this bundle are highly detailed and have been planned at length to ensure that students remain motivated and engaged whilst being constantly challenged on their current understanding. Links to previously-covered topics are also made throughout the lessons. The following specification points are covered in these lessons: TOPIC 5.1 * The light-dependent reaction of photosynthesis * The use of reduced NADP and ATP from the light-dependent reaction in the light-independent reaction * The light-independent reaction of photosynthesis * Environmental factors that limit the rate of photosynthesis TOPIC 5.2 * Respiration produces ATP * Glycolysis as the first stage of aerobic and anaerobic respiration * The conversion of pyruvate to lactate or ethanol in the anaerobic pathways * The link reaction and the Krebs cycle * Synthesis of ATP by oxidative phosphorylation * Other respiratory substrates TOPIC 5.3 * Gross primary production and net primary production * The net production of consumers * Farming practices designed to increase the efficiency of energy transfer TOPIC 5.4 * The role of microorganisms in the nitrogen cycle * The phosphorus cycle, including the role of saprobionts and mycorrrhizae * The use of artificial and natural fertilisers * The environmental issues arising from the use of fertilisers including leaching and eutrophication.
