This clear and concise lesson explores the roles of the coenzymes NAD, FAD and coenzyme A in cellular respiration as detailed in point 12.1 (d) of the CIE International A-level Biology specification.
As this specification point comes before the specification points concerning the details of the stages of respiration, this lesson has been designed to introduce the key details whilst focusing on their roles. Students will understand that NAD and FAD are reduced upon accepting hydrogen atoms and then carry these protons and electrons to the cristae where they are used in the production of ATP. In addition, they will learn that coenzyme A is used in the link reaction and helps to deliver the acetyl group to the Krebs cycle

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 14 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 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 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
