Anaerobic Respiration - Oxford AQA A Level Biology

Respiration - Oxford AQA A Level Biology

This bundle provides all the teaching resources required for the delivery of the Respiration topic (Chapter 20) of the Oxford AQA International A Level course. Having also taught AQA and Pearson Edexcel for a number of years I can confirm that these resources are also suitable for the delivery of this course. Through this series of 7 fully resourced lessons students will acquire knowledge and skills in the following areas: Lesson 1 - Glycolysis: Students will establish the role of glycolysis in cellular respiration. Lesson 2 - Anaerobic Respiration: Students will differentiate between anaerobic respiration in plants, microorganisms and animals. This includes an understanding of how lactate in animals and ethanol and carbon dioxide are produced in plants as well as how NAD is regenerated in order that ATP can continue to be produced in the absence of oxygen. Lesson 3 - The Link Reaction and Krebs Cycle: Students will determine the role of the link reaction and the Krebs Cycle in the production of ATP. Students will start by completing a reading application task, they will then apply their knowledge of respiration so far to a task on the inhibition of cyanide before studying the link reaction and Krebs cycle. Lesson 4 - The Electron Transfer Chain: Students will evaluate the chemiosmotic theory for ATP production. Students will start by recalling their prior knowledge of glycolysis, the link reaction and Krebs cycle before exploring the detailed events of the electron transfer chain. Lesson 5 - Respiratory Substrates: Students will determine the respiratory quotient of different respiratory substrates. Students will start by recalling their prior knowledge of biological molecules from AS Unit 1, they will then discuss how different respiratory substrates enter at different stages of respiration before exploring the equation and concept of respiratory quotients. Lesson 6 - Investigating Rate of Respiration (RP8): Students will investigate the effect of temperature on respiration in yeast. This lesson follows the suggested method for Oxford AQA International A Level Biology Required Practical 8. Students will be using the reduction of methylene blue as an indicator of respiratory rate. Through the starter activity I have included the set up of a respirometer as students are expected to know how they can be used to calculate respiratory quotients, although the practical method does not require this. Lesson 7 - Revision of Respiration: Students will consolidate their understanding of respiration through applying their understanding to unfamiliar scenarios and diagrams. Students will start by recalling their prior knowledge of the structure of mitochondria from AS Unit 1, they will then apply their understanding to a number of different past exam questions before finishing with a reflection of their progress, knowledge and understanding of this topic. Also included in this resource is a number of past paper questions from the student textbook that I have suggested students complete for further revision.
