Major pathways of glucose utilization CELLULAR RESPIRATION STAGES OF CELLULAR RESPIRATION • Glycolysis • The Krebs Cycle • The Electron Transport Chain (ETC) OVERALL EQUATION FOR CELLULAR RESPIRATION C6H12O6 + 6O2 6CO2 + 6H20 + ATP WHERE DOES CELLULAR RESPIRATION TAKE PLACE? It takes place in two parts of the cell Glycolysis occurs in the Cytoplasm Krebs Cycle & ETC take place in the Mitochondrion Mitochondrion CELLULAR RESPIRATION PROCESS Occurs across Cristae Occurs in Cytoplasm Occurs in Matrix Aerobic Cellular Respiration COENZYME A Co-Enzyme A – Carrier for Acetyl units in intermediate metabolism, fatty acid synthesis and oxidation  acetyl coA Glycolysis Glycolysis
