This is the revision page.

Here you will find topics taught in previous years, and materials useful to study for the final exam in October.


Topics:

  • Biodiversity and classification of living organisms

  • Cells

  • Plant structure and physiology: nutrition and transport

  • Human structure and physiology: nutrition and digestion - respiration and respiratory system - circulatory system and immunity - excretion and homeostasis

Transport across membranes

an animation on diffusion - the basics





Biological molecules


Enzymes
3 confusing words:

- catalyst (noun): a molecule that speeds up chemical reactions

- catalase (noun): an example of an enzyme

- catalyse (verb): to carry out a reaction
Memory trick: Catalase is a biological catalyst that catalyses the breakdown of hydrogen peroxide to water and oxygen.


Here's a simple mind map summarizing the main concepts.
