This fully-resourced lesson explores how pyruvate can be converted to lactate or ethanol using reduced NAD and that the reoxidation of the coenzyme allows glycolysis to continue. The engaging and detailed PowerPoint and accompanying differentiated resources have been designed to cover the third part of point 5.2 of the AQA A-level Biology specification which states that students should know the fate of pyruvate if respiration is only anaerobic.
The lesson begins with a focus on the coenzyme, NAD, and students are challenged to recall details of its role in the oxidation of triose phosphate. Students will learn that oxidative phosphorylation in aerobic respiration allows these coenzymes to be reoxidised but that another metabolic pathway has to operate when there is no oxygen. Time is taken to go through the lactate and ethanol fermentation pathways and students are encouraged to discuss the conversions before applying their knowledge to complete diagrams and passages about the pathways. Understanding checks in a range of forms are used to enable the students to assess their progress whilst prior knowledge checks allow them to recognise the links to earlier topics.

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

Another fantastic resource. Love the format and the students enjoy the activities. Thank you for sharing this.
Last day of term and I'm exhausted - needed something I could just pick up and use on this topic. Thank you.
Once again another brilliant resource from GJH education. This lesson and the others from this topic are packed with great information and extra handy tips for the pupils that are curious and/or need to be stretched and challenged. Pupils are kept engaged with the various activities, so definitely not a boring moment during the lessons.
Just what I was looking for. Thanks for sharing and for free!
Thank you for the excellent resources, both engaging & detailed.
