AQA Biology Paper 2 Revision Booklet (PART 2)

AQA Biology Paper 2 Revision Booklet (PARTS 1, 2 & 3)

These are three revision booklets to prepare AQA A Level Biology students for Paper 2 exams. Each booklet has every specification point broken down into smaller sections which contains: • the specification points so that students can prepare well for answering AO1 questions • clear and concise revision notes and diagrams on every specification point • recall questions and answers so students can practice their retrieval of key information • model answers to common exam questions • summary questions and answers • hints and tips to help students remember and understand tricky topics • practice exam questions and mark schemes **PART 1:** Contains 132 pages of revision material and exam practice on the first 2 topics: 3.6.4 Homeostasis is the maintenance of a stable internal environment 3.5.2 Respiration (including Required Practical 9) **Topic order:** Homeostasis GCSE recap of principles of homeostasis Importance of Homeostasis Controlling Blood Glucose Concentration Adrenaline and secondary messengers Kidney structure Osmoregulation and ADH Diabetes Respiration Mitochondria structure Glycolysis Link reaction Krebs Cycle Oxidative phosphorylation Respiratory Quotient and respiratory substrates RP9 Dehydrogenase activity in yeast cells method and exam questions **PART 2** Contains 114 pages of revision material and exam practice on the following topics: 3.6.2 Nervous coordination 3.5.3 Energy and ecosystems 3.5.4 Nutrient cycles **Topic order:** Nervous coordination GCSE recap on the structure and function of nervous systems Nerve structure Action potentials The synapse Summation Neuromuscular junctions The effect of drugs on the synapse Energy and ecosystems Energy in ecosystems Productivity and agriculture Nutrient cycles The nitrogen cycle The phosphorus cycle Fertilisers and eutrophication **PART 3** Contains 164 pages of revision material and exam practice on the following topics: 3.7.1 Inheritance 3.8.2 Gene expression is controlled by a number of features 3.5.1 Photosynthesis **Topic order:** Inheritance Key terms in genetics Monohybrid crosses Codominance Sex-Linkage Dihybrid crosses Autosomal Linkage Predicting Inheritance: Test crosses Investigating genetic ratios Probability of inheritance The Chi-Squared Test Gene expression Stem cells Regulation of gene expression Gene expression and cancer Epigenetics Photosynthesis Chloroplast ultrastructure Photosynthetic pigments Light dependent reactions: photolysis and photophosphorylation Light dependent reactions: The electron transport chain Light independent reactions: Calvin Cycle Limiting factors of photosynthesis
