For this practical I will see how temperature affects the rate of respiration with yeast. To do this I will conduct an experiment which will test this in the most fair and safe way.

Biology Practical Assessment Coursework Planning For this practical I will see how temperature affects the rate of respiration with yeast. To do this I will conduct an experiment which will test this in the most fair and safe way. My prediction for the experiment is that the yeast will respirate the most carbon dioxide at 40*C this is because yeast is an enzyme and we have enzymes in our body and they work best at our core body temperature which is 37*C. Yeast is a single celled organism and it uses sugar that is needed to react with the oxygen these react to respirate which produces three products; carbon dioxide, water and energy but to do this the molecules must collide. The molecules at different temperatures will have various collision rates this is how at which temperature the yeast will respirate best at. The higher the temperature the more collisions will occur which...
