Krebs+Cycle

__ KREBS CYCLE __
(FROM HAUSMANN NOTES)
 * Takes place in the **matrix** of the Mitochondria after Glycolysis
 * Completes the **decomposition** of Glucose
 * Completes the **oxidation** of Glucose into CO2, which is released as gasous waste
 * The Kreb's Cycle with Glycolysis also provide Carbon Skeletons for biosynthesis

 * Within the Krebs   cycle , energy in the form of ATP is usually derived from the breakdown of glucose, although fats and proteins can also be utilized as energy sources. Since glucose can pass through cell membranes, it transports energy from one part of the body to another.
 * The Krebs   cycle  affects all types of life and is, as such, the metabolic pathway within the cells, which chemically converts carbohydrates, fats and proteins into carbon dioxide and converts water into serviceable energy.


 * The Krebs   cycle  concerns the second of three major stages every living cell must undergo in order to produce energy, which it needs in order to survive. The enzymes that cause each step of the process to occur are all located in the cell’s “power plant.” In animals this is the mitochondria, in plants it is the chloroplasts, and in microorganisms it can be found in the cell membrane.


 * The Krebs   cycle  is also known as the citric acid  cycle  because citric acid is the very first product generated by this sequence of chemical conversions. (Dubroff)
