This fully-resourced lesson looks at the series of small steps that form the Krebs cycle and focuses on the reactions which involve decarboxylation and dehydrogenation and the reduction of NAD and FAD. The engaging PowerPoint and accompanying resource have both been designed to cover points 12.2 (d) and (e) of the CIE International A-level Biology specification.
The lesson begins with a version of the Impossible game where students have to spot the connection between 8 of the 9 terms and will ultimately learn that this next stage is called the Krebs cycle. The main part of the lesson challenges the students to use descriptions of the main steps of the cycle to continue their diagram of the reactions. Students are continually exposed to key terminology such as decarboxylation and dehydrogenation and they will learn where carbon dioxide is lost and reduced NAD and FAD are generated. They will also recognise that ATP is synthesised by substrate level phosphorylation. The final task challenges them to apply their knowledge of the cycle to work out the numbers of the different products and to calculate the number of ATP that must be produced in the next stage
This lesson has been designed to tie in with the other uploaded lessons on glycolysis, the Link reaction and oxidative phosphorylation.

Topics 12 & 13: Respiration and photosynthesis (CIE A-level Biology)
Respiration and photosynthesis are two of the most commonly-assessed topics in the terminal A-level exams but are often poorly understood by students. These 16lessons 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 fully prepared for these assessments. The following specification points in topics 12 and 13 of the CIE A-level Biology course are covered by these lessons: * The need for energy in living organisms * The features of ATP * The synthesis of ATP by substrate-level phosphorylation in glycolysis and the Krebs cycle * The roles of the coenzymes in respiration * The synthesis of ATP through the electron transport chain in the mitochondria and chloroplasts * The relative energy values of carbohydrates, lipids and proteins as respiratory substrates * Determining the respiratory quotient from equations for respiration * The four stages of aerobic respiration * An outline of glycolysis * When oxygen is available, pyruvate is converted into acetyl CoA in the link reaction * The steps of the Krebs cycle * Oxidative phosphorylation * The relationship between the structure and function of the mitochondrion * Distinguish between aerobic and anaerobic respiration in mammalian tissue and in yeast cells * Anaerobic respiration generates a small yield of ATP and builds up an oxygen debt * The products of the light-dependent stage are used in the Calvin cycle * The structure of a chloroplast and the sites of the light-dependent and light-independent stages of photosynthesis * The role of the chloroplast pigments * Absorption and action spectra * Using chromatography to separate the chloroplast pigments * The light-dependent stage of photosynthesis * The three stages of the Calvin cycle * The conversion of Calvin cycle intermediates to carbohydrates, lipids and amino acids * Explain the term limiting factor in relation to photosynthesis * Explain the effects of changes in light intensity, carbon dioxide concentration and temperature on the rate of photosynthesis * Explain how an understanding of limiting factors is used to increase crop yields in protected environments Due to the detail of these lessons, it is estimated that it will take up to 2 months of allocated A-level teaching time to cover the detail included in the slides of these lessons If you would like to sample the quality of the lessons, download the roles of the coenzymes, the Krebs cycle and the products of the Calvin cycle lessons as these have been shared for free

Topic 12: Energy and respiration (CIE A-level Biology)
Topic 12 tends to be the 1st topic to be taught in the second year of the CIE A-level Biology course and these 9 lessons are filled with a wide variety of differentiated tasks that will immediately engage and motivate the students whilst ensuring that the detailed content is covered. It is critical that students understand how energy in the form of ATP is produced by aerobic and anaerobic respiration and are able to describe the energy-driven reactions like active transport that need this input. For this reason, the lessons contain multiple understanding checks which assess the students on their current knowledge as well as checking on their ability to link to previously-covered topics. The following specification points in topic 12 of the CIE A-level Biology specification are covered in these lessons: * The need for energy in living organisms * The features of ATP that make this molecule suitable as the energy currency * Substrate-level phosphorylation in glycolysis and the Krebs cycle * The role of the coenzymes in respiration * The involvement of the electron transport chain that's found in the mitochondria and chloroplast membranes in the production of ATP * The four stages of aerobic respiration * Glycolysis * The link reaction * The Krebs cycle * Oxidative phosphorylation * The structure of the mitochondrion * The differences between aerobic and anaerobic respiration * The oxygen debt If you would like to sample the quality of these lessons, then download the roles of the coenzymes and the Krebs cycle lessons as these have been uploaded for free

Topic 12.2: Respiration (CIE International A-level Biology)
Each of the 6 lessons in this bundle are fully-resourced and have been designed to cover the content as detailed in topic 12.2 (Respiration) of the CIE International A-Level Biology specification. The specification points that are covered within these lessons include: * The stages of aerobic respiration and their location in eukaryotic cells * Glycolysis as the first stage of aerobic and anaerobic respiration * Pyruvate is converted to acetyl CoA in the Link reaction * The series of reactions that form the Krebs cycle * The process and details of oxidative phosphorylation * The relationship between structure and function in the mitochondrion * Anaerobic respiration in mammalian tissue and yeast cells * The oxygen debt 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 topics within this topic and earlier topics If you would like to see the quality of the lessons, download the Krebs cycle lesson which are free

Great help to my students who are struggling. I used it to reinforce knowledge they had from another teacher. Good detail and activities.
I was looking for something to help my students who are doing the OCR course and stumbled upon this. It matches well with my course and used it this week with my class. Due to the way the lesson is broken down all the students were able to to understand the cycle. I especially, like the AFL aspects of the lesson.
