AQA Biology Revision

Possible questions

They are going to be pretty open questions.

So, what are the types of questions that could come up? (Thanks to arvin_infinty for starting this) 

You could write an essay about each one, but thats alot of writing and as it probably won't be able to get it marked by an examiner then it may have limited use repeatedly writing out essays for each of these titles.Although if you have done one you could try posting it in the guestbook for others to read. Or you could come up with topics and idea that you could include in each one. For example "The different ways in which organisms use ATP" you may want to include : photosynthesis (dependent/independent and possibly factors affecting), what organisms use energy for (metabolism producing heat, movement, active transport, division, production of stuff, maintaining body temp) and then could go into further detail for example nerves and creating resting potential, movement of blood around the body, movement of organism away from predators. And of course respiration, from the activation of glucose to make phosphororylated glucose in glycolysis tohow the electron transport chain produces ATP.You would also have to stick in the old faithfull ATP + (H2O) ---->ADP + Pi +Energy. There is also the use of ATP as a second messenger when it is converted into cyclic AMP by an activated enzyme from adrenaline. Should probably include something on muscles if aswell, something about the myosin giving head to the actin then using ATP to move it, yea you read me correctly, you won't forget that in a hurry. One down 21 left =)

 

 1. How is structure of cells is related to their function?


2. The different ways in which organisms use ATP.
 

3. How do bacteria affect human lives?


4. What is biological importance of water?


5. Describe the transfer of energy between different organisms and between these organisms and the environment.

6. In which ways do different species of organisms differ from each other and why?


7.What is Negative Feedback and whats it's importance in biology?


8. Condensation and hydrolysis and their importance in biology and the body.


9. Inorganic ions include those of sodium, phosphorus and hydrogen. Describe how these and other inorganic ions are used in living organism.

10. Polymers have different structures, they also have different functions. Describe how the structures of different polymers are related to their functions.

11. Describe how nitrogen-containing substances are taken into, and metabolised in, animals and plants.

12. Carbon dioxide in organisms and ecosystems.

13. Why offspring produced by the same parents look different in appearance.

14. What cycles are important for biologists to consider when looking at nature and why?

15. Describe and explain the uses of genetic engineering in Medical Science.

 
16. How is the structure of protein is related to the function?

17. How do substances travel within the body and why?

18. The structure and function of carbohydrates.

19. Carbon dioxide may affect organisms directly or indirectly. Describe and explain these
effects.

20.The causes of disease in humans. 

21.Mean temperatures are rising in many parts of the world. The rising temperatures mayresult in physiological and ecological effects on living organisms. Describe and explain these effects.

22.The causes of variation and its biological importance.

23.Transfers through ecosystems.

24.Movements inside cells.

25. The movement of carbon.

 

Or you could just steal mine :)
