INVESTIGATING THE EFFECTS OF TEMPRATURE ON THE RATE OF ANAEROBIC RESPIRATION OF YEAST Since this experiment discusses the effects of temperature on the rate of anaerobic respiration, I think it is sensible to first talk about anaerobic respiration. 'When free oxygen is not present, hydrogen cannot be disposed of by combination with oxygen.'(1) This stops the electron transfer chain, inhibiting the production of ATP. In organisms like yeast, the synthesis of ATP can continue in the absence of oxygen. This can be achieved by a process that takes place in the cytoplasm called ethanol pathway, which is a type of anaerobic respiration. The hydrogen released from reduced NAD is passed to ethanal reducing it to ethanol, making it possible for glycolysis to continue. However, this process does not produce as many ATP molecules as aerobic respiration (anaerobic respiration produces 2 molecules of ATP, in contrast with a possible number of 38...
