INVESTIGATING THE EFFECT OF GLUCOSE CONCENTRATION ON THE RATE OF REPRODUCTION OF YEAST CELLS Prediction In this section I will look at all the factors involved in the rate of reproduction of yeast cells, bring them together at the end of the section and deduct a scientific conclusion as to what I would expect to happen. Yeast Cell Respiration Yeast cells, like any other organism, need a substrate to respire. Respiration in general In respiration, they use the substrate to produce ATP for cell metabolism. The overall equation for respiration using glucose is: C6H12O6 + 6O2 Þ 6CO2 + 6H2O Figure 1: Aerobic respiration in detail Therefore, the more glucose available, the greater the rate of respiration and the easier it is for cell metabolism to take place. The more detailed version of the respiratory pathway is shown in Figure 1. However, one cannot merely assume that a greater rate of respiration can occur with a higher level...
