Cellular Respiration – Chapter 7 How do organisms use energy? - work in cells uses ATP - ATP has to be replaced - Glucose, glycogen etc. broken down to make more ATP - Requires many steps but occurs quickly  Cellular Respiration - The metabolic pathway where cells harvest energy from metabolism of  food molecules - Glucose is one of the main food molecules used - Grouped into three different stages: 1. Glycolisis 2. Krebs Cycle 3. Electron Transport system Cellular Respiration – overview 1. Glycolysis The most widespread metabolic pathway Glucose split into two 3-carbon compounds Hydrogens stripped from carbons Occurs in cytoplasm of cell (not mitochondria) Requires no organelles Requires no oxygen (the anaerobic metabolic pathway) 2. Krebs Cycle Occurs in Mitochondria of cells
