Testing Cell Respiration and Alcoholic Fermentation

There will be a measurement of heat generation produced by seedlings during cell respiration. Using a thermometer, the heat of seedlings in a thermos bottle will be calculated over a period of at least 25 minutes in 5-minute increments. Using indicator TTC you will also be able to distinguish viable seeds. Along with studies of cell respiration through temperature readings there will also be investigation of alcoholic fermentation in yeast. A respirometer will be constructed for …

…electrons they are available for electron transport systems. Their energy is used fro a proton gradient. The third part of glucose metabolism is the electron transport and chemiosmotic phosphorylation. This is the use of free energy of electrons that produce a proton gradient, which is used for the formation of ATP. Located along the inner membrane of the mitochondrion are numerous electron transport systems. When NADH reduces FMN it receives two electrons and two protons.
