Lecture 12 – Glucose Oxidation I – Glycolysis A. Cellular Respiration 1. Overall Reaction 6 H 2 O + 6O 2 + C 6 H 12 O 6 6CO 2 + 12H 2 O + available energy a. Glycolysis Take glucose (6 carbons) and form 2 pyruvic acids (P.A. 3 carbons each) o Glucose 2 PA o Occurs in the cytoplasm o Glucose 6 PO 4 is changed from combining with Glucose Transporter 1 b. Formation of acetyl Co-A Take 2 PA and form 2 Acetyl CO-A Occurs in mitochondria (considered aerobic respiration) c. Citric Acid Cycle Kreb’s Cycle Occurs in mitochondria (considered aerobic respiration) d. Electron transport system and Chemiosmosis Occurs in mitochondria (considered aerobic respiration) 2. Glycolysis - Occurs in cytoplasm - Can occur without oxygen (anaerobic or aerobic) Most primitive set of reactions o Before world formed oxygen - Common in all organisms - Enzymes for this reaction are arranged on the cytoskeleton 3. Glycolysis Steps (fig. 8-4)
