AQA Biology trilogy edition textbook-Page 184-185. Students are required to know the following; Students should be able to describe genetic engineering as a process which involves modifying the genome of an organism by introducing a gene from another organism to give a desired characteristic. Plant crops have been genetically engineered to be resistant to diseases or to produce bigger better fruits. Bacterial cells have been genetically engineered to produce useful substances such as human insulin to treat diabetes. Students should be able to explain the potential benefits and risks of genetic engineering in agriculture and in medicine and that some people have objections. In genetic engineering, genes from the chromosomes of humans and other organisms can be ‘cut out’ and transferred to cells of other organisms. Crops that have had their genes modified in this way are called genetically modified (GM) crops. GM crops include ones that are resistant to insect attack or to herbicides. GM crops generally show increased yields. Concerns about GM crops include the effect on populations of wild flowers and insects. Some people feel the effects of eating GM crops on human health have not been fully explored. Modern medical research is exploring the possibility of genetic modification to overcome some inherited disorders. (HT) Students should be able to describe the main steps in the process of genetic engineering. In genetic engineering: • enzymes are used to isolate the required gene; this gene is inserted into a vector, usually a bacterial plasmid or a virus • the vector is used to insert the gene into the required cells • genes are transferred to the cells of animals, plants, or microorganisms at an early stage (egg or embryo) in their development so that they develop with desired characteristics.

AQA Biology third edition textbook-Page 140-141 Students are required to know the following; Students should be able to explain the importance of sugars, amino acids, fatty acids and glycerol in the synthesis and breakdown of carbohydrates, proteins and lipids. Metabolism is the sum of all the reactions in a cell or the body. The energy transferred by respiration in cells is used by the organism for the continual enzyme controlled processes of metabolism that synthesise new molecules. Metabolism includes: •conversion of glucose to starch, glycogen and cellulose •the formation of lipid molecules from a molecule of glycerol and three molecules of fatty acids • the use of glucose and nitrate ions to form amino acids which in turn are used to synthesise proteins • respiration •breakdown of excess proteins to form urea for excretion. All of these aspects are covered in more detail in the relevant specification section but are linked together here.

Food tests (RP 4-separate science). This practical was completed in one lesson, students were asked to construct a graph from their data for homework. How did i deliver this practical? Groups of 3, each group needs a test tube rack, 3 x test tubes and 1 x boiling tube. Goggles must be worn throughout the practical. Circus activity-students visited a station to complete a food test (avoids too many students doing the same test or taking all the reagents). Instead of using a hot water bath for the simple sugars test i lit a bunsen burner and allowed students to heat their solution in a boiling tube, holding it at a slant near the flame using tongs. Students really enjoyed this and the colour change is very sudden. Only one bunsen burner needs to be on for this and can be manned by the teacher to prevent misuse.
