Cellular Respiration: The process by which mitochondria ...



Cellular Respiration: The process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. P.222 1 molecule of glucose

-3 stages: Glycolysis =2 ATP

Citric Acid Cycle =2 ATP

Electron Transport Chain =32 ATP

Total=36 ATP

Glycolysis: Series of chemical reactions in the cytoplasm of a cell that break down glucose, a six-carbon compound, into two molecules of pyruvic acid, a three-carbon compound. P.223

Citric acid cycle: (Krebs Cycle) A series of chemical reactions that break down glucose and produce ATP; energizes electron carriers that pass the energized electrons on to the electron transport chain. For every turn of the cycle 1 molecule of ATP & 2 molecules of CO2 are produced. P. 226

Electron Transport Chain: (Mitochondrion) uses the high-energy electrons from the krebs cycle to convert ADP into ATP. P. 228

Fermentation: during heavy exercise, when your cells are without oxygen. This anaerobic process follows glycolysis and provides a means to continue producing ATP until oxygen is available. P.224

Two types of Fermentation:

-Lactic Acid Fermentation: One of the processes that supply energy when oxygen is scarce. Two molecules of pyruvic acid produced in glycolysis use NADH to form two molecules of lactic acid. Results in muscle fatigue. P.224

-Alcoholic Fermentation: used by yeast cells and some bacteria to produce CO2 and ethyl alcohol. P. 224
