IAL Edexcel Biology (2018) Unit 1 (WBI11) Last Minute Revision: Molecules, Diet, Transport and Health [Part 1]

Image
 Preface This series contains 5 pars which are divided into 2 videos for topic 1 - molecules, transport and health; 2 videos for topic 2 - membranes, proteins, DNA and genes expression; and biology practical. The revision will be based on the syllabus for (WBI11) IAL Edexcel Biology (2018) Unit 1 The first part contains the first half of the syllabus for topic 1 Syllabus Checklist Understand the importance of water as a solvent in transport, including its dipole nature  Know the difference between monosaccharides, disaccharides and polysaccharides, including glycogen and starch (amylose and amylopectin)  Be able to relate the structures of monosaccharides, disaccharides and polysaccharides to their roles in providing and storing energy  Know how monosaccharides (glucose, fructose and galactose) join together to form disaccharide (maltose, sucrose and lactose) and polysaccharides (glycogen, amylose and amylopectin) through condensation reactions forming glycosidic bon...

The revision will be based on the syllabus for (WBI11) IAL Edexcel Biology (2018) Unit 1 The third part contains the first half of the syllabus for topic 2 Syllabus Checklist 1. Know the properties of gas exchange surfaces in living organisms (large surface area to volume ratio, thickness of surface and difference in concentration) 2. Understand how the rate of diffusion is dependent on these properties and can be calculated using Fick’s Law of Diffusion 3. Understand how the structure of the mammalian lung is adapted for rapid gaseous exchange 4. Know the structure and properties of cell membranes 5. Understand how models such as the fluid mosaic model of membrane structure are interpretations of data used to develop scientific explanations of the structure and properties...

The revision will be based on the syllabus for (WBI11) IAL Edexcel Biology (2018) Unit 1 The second part contains the remaining  of the syllabus for topic 1 Syllabus Checklist 13. Understand the blood clotting process (thromboplastin release, conversion of prothrombin to thrombin and fibrinogen to fibrin) and its role in cardiovascular disease (CVD) 14. Know how factors such as genetics, diet, age, gender, high blood pressure, smoking and inactivity increase the risk of cardiovascular disease (CVD) 15. Understand the link between dietary antioxidants and the risk of cardiovascular disease (CVD) 16. Be able to analyse and interpret quantitative data on illness and mortality rates to determine health risks, including distinguishing between correlation and causation and rec...
