Analysis of Paper Three 2005-2009

Please use your own judgement to decide what are the possibilities of Paper 3 questions this year 2010...

*You may use this simple analysis to decide !...If you dare to forecast :-)

2005:

Qs 1- Energy value (F4)

Qs 2-Isotonic solution (F4)

2006:

Q1-Different CONCENTRATION OF SUBSTRATE affects on the rate of enzyme PEPSIN (F4)

Q2- AGAIN---Isotonic solution (F4)

2007:

Q1- Effect of LIGHT INTENSITY on the rate of photosynthesis.(F4)

Q2-Effect of TEMPERATURE on THE RATE OF ANAEROBIC RESPIRATION IN YEAST. (F4)

2008:

Q1- The population of Pleurococcus affected by abiotic factor :LIGHT INTENSITY. (F4)

Q2- Molecules size and its affect on rate of diffusion through a semi permeable membrane. (F4)

2009:

Q1- AGAIN---REPEAT 2007 !! Effect of light intensity on the rate of photosynthesis. (F4)

Q2- Effect of cold water and hot water on enzyme activity. (F4)

So...you see guys...Its not easy to forecast this paper..Looks like it is always from the Form 4 Chapters!... enzymes, photosynthesis, isotonic...have been repeatedly asked!

I would advise you to know the technique of answering this paper WELL..Then you dont have to worry what questions will be asked because you already master the format of answering it..

Paper 3 is a must score paper...Its not difficult..The questions are sure within the scope of Biology syllabus.

Maybe what you have done for your PEKA Biology could help you to understand more the experiments involved..

Or else you can start imagining doing experiment, but the format must always be like this:

Result:

Conclusion:

HAPPY REVISING :-)
