This detailed lesson looks at the structure of the mitochondrion and explains how the specific features allow the stages of aerobic respiration to take place in this organelle. The engaging PowerPoint and accompanying resource have been designed to cover point 5.2.2 (b) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the inner and outer mitochondrial membranes, cristae, matrix and mitochondrial DNA.
The lesson begins with a version of “GUESS WHO” where students have to use a series of structural clues to whittle the 6 organelles down to just 1 - the mitochondrion. Moving forwards, the key components of the organelle are identified on a diagram. Students are introduced to the stages of respiration so that they can make a link to the parts of the cell and the mitochondria where each stage occurs. Students will learn that the presence of decarboxylase and dehydrogenase enzymes in the matrix along with coenzymes and oxaloacetate allows the Link reaction and the Krebs cycle to run. Finally, time is taken to introduce the electron transport chain and the enzyme, ATP synthase, so that students can begin to understand how the flow of protons across the inner membrane results in the production of ATP.
This lesson has been designed to tie in with the other uploaded lessons on the stages of respiration.

Module 5.2: Photosynthesis & Respiration (OCR A-level Biology A)
Photosynthesis and respiration 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 prepared for these assessments. The following specification points in modules 5.2.1 and 5.2.2 of the OCR A-level Biology A course are covered by these lessons: * The structure of a chloroplast and the sites of the two main stages of photosynthesis * The light-dependent stage of photosynthesis * The fixation of carbon dioxide and the light-independent stage of photosynthesis * The uses of triose phosphate * Factors affecting photosynthesis * The need for cellular respiration * The structure of the mitochondrion * The process and site of glycolysis * The link reaction and its site in the cell * The process and site of the Krebs cycle * The importance of coenzymes in cellular respiration * The process and site of oxidative phosphorylation * The chemiosmostic theory * The process of anaerobic respiration in eukaryotes * The relative energy values of carbohydrates, lipids and proteins as respiratory substrates * The use of the respiratory quotient Due to the detail of these lessons, it is estimated that it will take in excess of 2 months of A-level lessons to cover this module If you would like to sample the quality of the lessons, download the uses of triose phosphate, link reaction and respiratory substrates lessons as these have been shared for free

Module 5.2.2: Respiration (OCR A-level Biology A)
All 9 of the lessons included in this bundle are fully resourced and have been designed to cover the detailed content of module 5.2.2 (Respiration) of the OCR A-Level Biology A specification. The following specification points are covered by this bundle of lessons: * The need for cellular respiration * The structure of the mitochondrion * The process and site of glycolysis * The link reaction and its site in the cell * The process and site of the Krebs cycle * The importance of coenzymes in cellular respiration * The process and site of oxidative phosphorylation * The chemiosmotic theory * The process of anaerobic respiration in eukaryotes * The difference in the relative energy values of carbohydrates, lipids and proteins * The use and interpretation of the respiratory quotient All of the lessons are detailed and engaging and contain regular progress checks so that students can assess their understanding of the current topic as well as prior knowledge checks to enable links between topics and modules to be seen It is estimated that these lessons will cover in excess of a month's A-level Biology teaching time
