This powerpoint presentation covers Topic 3.2 in the IB Biology curriculum. Specifically, it covers the basic biomolecules , how they are formed and their functions (see learning objectives).
Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes. The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
**IB Biology Learning Objectives:
3.2.1 – Distinguish between organic and inorganic compounds.
3.2.2 – Identify amino acids, glucose, ribose and fatty acids from diagrams showing their structure.
3.2.3 – List three examples each of monosaccharides, disaccharides and polysaccharides.
3.2.4 – State one function of glucose, lactose and glycogen in animals, and of fructose, sucrose and cellulose in plants.
3.2.5 – Outline the role of condensation and hydrolysis in the relationships between monosaccharides, disaccharides and polysaccharides; between fatty acids, glycerol and triglycerides; and between amino acids and polypeptides
3.2.6 – State three functions of lipids.
3.2.7 – Compare the use of carbohydrates and lipids in energy storage.
