New Edexcel IGCSE 9-1 4BI1 syllabus for 2017
Section 2c Biological molecules
2.7 Identify the chemical elements present in carbohydrates, proteins and lipids (fats and oils).
2.8 Describe the structure of carbohydrates, proteins and lipids as large molecules made up from smaller basic units: starch and glycogen from simple sugars, protein from amino acids, and lipid from fatty acids and glycerol.
2.9 Practical: investigate food samples for the presence of glucose, starch, protein and fat.
2.10 Understand the role of enzymes as biological catalysts in metabolic reactions.
2.11 Understand how temperature changes can affect enzyme function, including changes to the shape of active site.
2.12 Practical: investigate how enzyme activity can be affected by changes in temperature.
2.13 Understand how enzyme function can be affected by changes in pH altering the active site.
2.14B Practical: investigate how enzyme activity can be affected by changes in pH. (In orange)
New for IGCSE 4BIO1 - More practical pages, updated design, concept checker and exam style question for each topic.
