Felix Simpeh Biology Coursework Factors that affect the respiration of immobilised yeast Date Completed: Thursday, 20 March 2003 To start off this experiment I feel that it is suitable to explain the main facts of this study. Below is a section explaining respiration and immobilised yeast in detail. Like all living organisms, yeast has to make energy, stored as ATP to carry out all cellular functions. To do this they can respire aerobically when there is plenty of oxygen, or anaerobically where oxygen is short, by this, they are called partial anaerobes. This produces less energy, but keeps the yeast alive. Pyruvic acid has to be broken down in respiration when formed by breaking down of glucose molecules, this can't be done in the same way as it is aerobically when respiring anaerobically which is how the carbon dioxide and ethanol is formed through the zymase. Here is the equation for the aerobic respiration: - Glucose...
