Scott Mabbutt Biology investigation: Investigating the effect of glucose concentration on the respiration of yeast Aim The aim of this investigation is to find out how concentration of glucose affects the respiration of yeast. Introduction Yeast are a single cell species of the kingdom fungi, and has commonly utilised by humans to produce bread, wine and beer for thousands of years. In order to produce the energy that yeast needs to perform cellular processes, it has to metabolise glucose. Essentially the Glucose is turned into energy in the form of ATP. I plan to investigate how the concentration of the metabolic substrate affects the rate at which it is metabolised. I will do this by measuring the gas given off as a by-product of respiration, CO2. I will hope to gain quantitative evidence to back up a prediction I make. The equipment I will need is: * Test tubes x 6 * Boiling tubes x 6 *...
