PPT-Oxidative Decarboxylation and Krebs Cycle

Objectives Oxidative Decarboxylation By the end of this lecture students are expected to Recognize the various fates of pyruvate Define the conversion of pyruvate to acetyl CoA Discuss the major regulatory mechanisms for PDH complex. Springfield Central High School. 2009. Photosynthesis and Respiration. Chloroplasts and Mitochondria. Chloroplasts are the site of photosynthesis.. Know these structures:. Thylakoid, . Granum. , . Stroma. 1.Glycolysis 2.Transition 3.Krebs cycle 4.Electron transport system These phases are nothing more than metabolic reactions involvingthe conversion of glucose & other molecules into carbon dioxide & wa Under aerobic conditions, pyruvate enters the mitochondria where it is converted into acetyl CoA.. Acetyl CoA is the fuel for the citric acid cycle, which processes the two carbon acetyl unit to two molecules of CO. Respiration . Let’s Review. Is a chemical process that uses oxygen to convert chemical energy stored in organic molecules into another form of chemical energy – a molecule called ATP. Cells in plants and animals then use the ATP as their main energy supply.. Pages 213-220. Aerobic Cellular Respiration. Mitochondria. Round or sausage shaped organelle. Specialize in the production of large quantities of ATP. Site of aerobic cellular respiration. ATP production requires free oxygen. Food is the energy source for cells. The energy in food is measured in . calories.. A . calorie. . is the amount of energy needed to raise the temperature of 1 gram of water 1 degree Celsius. There are 3811 calories in one gram of sugar glucose.. Anju. .M.P. BCH.10.05.12. One of the paradoxes of life on this planet is that the molecule that sustains aerobic life, oxygen, is not only fundamentally essential for energy metabolism and respiration, but it has been implicated in many diseases and degenerative conditions.
