AQA A level Biology Specificaton Unit 1 Biological Molecules Topic: 1.4.2 Many proteins are enzymes NOT THE REQUIRED PRACTICAL This lesson covers: Each enzyme lowers the activation energy of the reaction it catalyses. The induced-fit model of enzyme action. The properties of an enzyme relate to the tertiary structure of its active site and its ability to combine with complementary substrate(s) to form an enzyme-substrate complex. • The specificity of enzymes • The effects of the following factors on the rate of enzymecontrolled reactions – enzyme concentration, substrate concentration, concentration of competitive and of noncompetitive inhibitors, pH and temperature. Students should be able to: • appreciate how models of enzyme action have changed over time • appreciate that enzymes catalyse a wide range of intracellular and extracellular reactions that determine structures and functions from cellular to whole-organism level. To complete the lesson provide students with related past exam questions

The PowerPoint can be printed, cut and folded to produce a series of double sided flashcards to help students memorise the equations needed for the physics exam. You need to print the slides below with 2 slides per page (big version) or 6 slides per page (mini version). There are twenty two equations as power, energy transferred and time appear twice on the AQA spec equation sheet. Cut each box out and fold along the dashed line to create back to back flash cards. On each card you are given the name of the variables that you should be able to identify in the exam question. On one slide you have the matching units that you need to memorise to check if you need to convert any values in the exam question. On the second slide you have the equation triangle, that you need to memorise, so you can rearrange the equation and answer the question.

AQA A level Biology Specificaton Unit 1 Biological Molecules Topic: 1.3 Lipids This lesson covers: Triglycerides and phospholipids are two groups of lipid Triglycerides are formed by the condensation of one molecule of glycerol and three molecules of fatty acid A condensation reaction between glycerol and a fatty acid (RCOOH) forms an ester bond The R-group of a fatty acid may be saturated or unsaturated In phospholipids, one of the fatty acids of a triglyceride is substituted by a phosphate-containing group The different properties of triglycerides and phospholipids related to their different structures The emulsion test for lipids Students should be able to: recognise, from diagrams, saturated and unsaturated fatty acids explain the different properties of triglycerides and phospholipids.

AQA A level Biology Specificaton Unit 1 Biological Molecules Topic: 1.4.1 Proteins This lesson covers: Amino acids are the monomers from which proteins are made. The general structure of an amino acid NH2 represents an amine group, COOH represents a carboxyl group and R represents a side chain. The twenty amino acids that are common in all organisms differ only in their side group. A condensation reaction between two amino acids forms a peptide bond. Dipeptides are formed by the condensation of two amino acids. Polypeptides are formed by the condensation of many amino acids. A functional protein may contain one or more polypeptides. The role of hydrogen bonds, ionic bonds and disulfide bridges in the structure of proteins. Proteins have a variety of functions within all living organisms. The relationship between primary, secondary, tertiary and quaternary structure, and protein function. The biuret test for proteins. Students should be able to relate the structure of proteins to properties of proteins named throughout the specification. To complete the lesson provide students with related past exam questions

Presentation on monosaccharides, disaccharides, polysaccharides and starch/reducing and non reducing sugar tests. AQA A level Biology Specificaton Unit 1 Biological Molecules Topic: 1.1 Monomers and Polymers, 1.2 Carbohydrates This material covers: Monosaccharides are the monomers from which larger carbohydrates are made. Glucose, galactose and fructose are common monosaccharides. A condensation reaction between two monosaccharides forms a glycosidic bond. Disaccharides are formed by the condensation of two monosaccharides: • maltose is a disaccharide formed by condensation of two glucose molecules • sucrose is a disaccharide formed by condensation of a glucose molecule and a fructose molecule • lactose is a disaccharide formed by condensation of a glucose molecule and a galactose molecule. Glucose has two isomers, α-glucose and β-glucose, with structures: Polysaccharides are formed by the condensation of many glucose units. • Glycogen and starch are formed by the condensation of αglucose. • Cellulose is formed by the condensation of β-glucose. The basic structure and functions of glycogen, starch and cellulose. The relationship of structure to function of these substances in animal cells and plant cells. Biochemical tests using Benedict’s solution for reducing sugars and non-reducing sugars and iodine/potassium iodide for starch.
