You will find a whole list of sites that will be useful in building your understanding of relevant concepts. Feel free to add comments in the discussion section of this page or below each site about how useful it is or whether you recommend it. If you come across a site then please add it to the list. Write a brief description of why it is relevant and perhaps even give it a rating out of 5.

[|Biology mad] Great site with lots of information on a whole range of topics that are relevant, including biomolecules, enzymes, cell cycle and immune system. (3.5/5)
 * GENERAL SITES (multiple topics)**

[|Biocourse] This is the homepage for a site that covers many areas. You will find useful QuickTime movies in the **Cell structure and function** and **Membrane structure and function** sections. (4/5)

[|Wiley] This is the homepage of an excellent site covering many topics. Click on the central dogma of biochemistry to get an overview of how DNA results in proteins being made. (4/5)

[|Wisconsin online] You can access a range of animations on different topics that I have placed into my favourites section fo this site. (4/5)

[|Life-the science of biology] Lots of stuff from quizzes, interactive tutorials, animations etc. aimed at uni level but still worth while for you guys (3.5/5)

These animations are courtesy of a Wisconsin uni site. You can acess a whole stack of learning objects (animations) by creating an account (email and password) or just use the links below. [|Biomolecules-the carbohydrates] [|Biomolecules-the lipids] [|Biomolecules-the proteins] These three give a pretty straightforward overview of these groups of organic substances. Not much detail though. (3/5)
 * BIOMOLECULES AND MEMBRANES**

[|Peptide bonds-condensation polymerisation] Useful in showing how water is produced, the same thin applies to joining of monosaccharides or nucleotides, except they are called different types of bonds. (3/5)

[|Plasma membrane] good recap of membrane structure and also tests your knowledge. (3/5)

[|Active transport] Good account all ATP driven processes, including endocytosis (different types) and exocytosis. Need to be familiar with all of these. (4/5)

[|Osmosis] [|Diffusion] These two cover passive transport across a membrane. Pretty simple account. (2.5/5)

[|Movement across membranes] Check out the animations on Na-K pump and endo- and exocytosis. (4/5)

[|Movement across membranes] You can all thank one of the year 11s for finding this site. It is great. Covers alot of different aspects of movement. An absolute must to check out. (5/5)

[|Protein structure] Gives a simple account of the three dimensional nature of protein structure. Need to scroll down towards the bottom fo the page. (4/5)


 * METABOLIC PATHWAYS**

[|Enzymes] Two animations on biochemical pathways that give a good overview. Really worth a look.(4/5)

[|Photosynthesis] Good overview of the process, you may find this useful. (4/5)

[|Respiration] Like above a useful summary of the process with good detail. Although some of the terminology is not the same as we will use. (3.5/5)

[|Respiration animation] Quite a good summary, does go quickly though and doesn't have text to read. (3.5/5)

[|Electron Tansport Chain and Chemiosmosis animation] Gives you a visual idea of what is happening in the final stages of aerobic respiration where most ATP is produced. (3.5/5)

[|Metabolic pathways] Simple animation of the overall process. Worth a look because it shows the difference between aerobic and anaerobic. (3/5)


 * PROTEINS AND PROTEOMICS**

[|Protein synthesis animation] Good simple account of the basics that you need to be familiar with in Unit 3. (4/5)


 * NERVOUS SYSTEM**

[|how neurons work] Excellent animation on the complexity of the brain and shows a really good animation on synaptic transmission. Definitely worth a look.(4/5)

[|synapse animation] Good simple animation of synaptic transmission.(3/5)

[|synapse and vesicles] Quite a simple overview of a synapse and the release of neurotransmitters. Scroll down to about 13th and 14th from bottom to find the apprpriate animations.(3/5)

[|chemical synapse] Clear animation of a chemical synapse. Definitley worth a look. (4/5)


 * ENDOCRINE SYSTEM**

[|pathophysiology of the endocrine system] good overview of the endocrine system, lots of detial and relevant stuff. (4/5)

[|Steroid hormone action] good overview that summarises the importnat concepts and easy to follow. (4/5)

[|Thyroxine action] another simple account that shows how lipophilic hormones can bind to receptors in nucleus. (3/5)

[|Epinephrine action] Another clear account showing how a water-soluble hormone (epinephrine also called adrenaline) affects a cell. You should be able to clearly distinguish between the different modes of action of hormones (depedning on their chemical nature. It also goes into signal transduction. You needn't worry about all the detailed steps just the overall idea. (4/5)

SIGNAL TRANSDUCTION

[|second messenger] Excellent animation showing an overview of the role of second messengers. You do not need to remember actual molecules, just be able to make sense of the overall process. (4/5)
