This detailed and clear lesson describes and explains how the electron transport chain and the chemiosmotic theory are involved in the synthesis of ATP by oxidative phosphorylation. The PowerPoint has been designed to cover the sixth part of point 5.2 of the AQA A-level Biology A specification and also looks at the role of the enzyme, ATP synthase.
The lesson begins with a discussion about the starting point of the reaction. In the previous stages, the starting molecule was the final product of the last stage but in this stage, it is the reduced coenzymes which release their hydrogen atoms. Moving forwards, the process of oxidative phosphorylation is covered in 7 steps and at each point, key facts are discussed and explored in detail to enable a deep understanding to be developed. Students will see how the proton gradient is created and that the flow of protons down the channel associated with ATP synthase results in a conformational change and the addition of phosphate groups to ADP. Understanding checks are included throughout the lesson to enable the students to assess their progress.
This lesson has been written to tie in with the other uploaded lessons on glycolysis, the Link reaction and Krebs cycle and anaerobic respiration.

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 of the 13 lessons that are 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 If you would like to sample the quality of the lessons in this bundle, then download the chloroplast structure, anaerobic respiration, oxidative phosphorylation and GPP lessons as these have 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 5.2: Respiration (AQA A-level Biology)
All 7 of the lessons in this bundle are fully-resourced and have been designed to cover the content as detailed in topic 5.2 (Respiration) of the AQA A-Level Biology specification. The specification points that are covered within these lessons include: * Respiration produces ATP * Glycolysis as the first stage of aerobic and anaerobic respiration * The phosphorylation of glucose and the production and oxidation of triose phosphate * The production of lactate or ethanol in anaerobic conditions * The Link reaction * The oxidation-reduction reactions of the Krebs cycle * The synthesis of ATP by oxidative phosphorylation * The chemiosmotic theory * Lipids and proteins as respiratory substrates The lessons have been written to include a wide range of activities and numerous understanding and prior knowledge checks so students can assess their progress against the current topic as well as be challenged to make links to other sub-topics within this topic and earlier topics If you would like to see the quality of the lessons, download the anaerobic respiration and oxidative phosphorylation lessons as these have been uploaded for free
