The rate of respiration in yeast and how it is affected by temperature. Science Biology: Planning For my coursework I am going to investigate how temperature can change the rate of respiration on yeast. I shall do this by conducting an experiment which will involve the timing of the yeast, water and glucose. I shall time how long it takes for the yeast mixture to respire 10 bubbles. I have chosen yeast because it responds quite quickly so it doesn't take all day. When I chose yeast I was aware of the factors that will affect enzymes and living things. These are: * Temperature * Oxygen availability * Glucose availability * PH * Radiation (Not in my experiment) * Water * Concentration Preliminary Work I discovered that the PH in the experiment denatures the enzyme as do other enzymes and temperature. Anaerobic respiration is the production of carbon dioxide without the use of oxygen. So all living things need...
