Digestion and Respiration MMHS Anatomy Chitraroff • Catabolism: Breakdown reaction of large to small molecules. (=digestion) releases energy (ATP created) • Anabolic : Synthesis reaction (=creation) requires energy (ATP used) • Metabolism : Sum reactions of catabolism & anabolism. CARBOHYDRATES Glycogen PROTEINS Polypeptides LIPIDS Triglycerides Glucose Lipogenesis Lipolysis Glycolysis Glucogensis Amino Acids Fatty Acids Glycerol Pyruvic Acid O2 H2O Fatty Acids Break down oxidation Electron Transport System Acetyl-CoA Krebs Cycle Mitochondrion (Aerobic Respiration) CO2 Waste Heat = 32 ATP per Glucose 1 ATP/Cycle (=Burning the Food) Glucose + Oxygen (Reactants) (Reaction) CO2 + H2O + Heat (Products) • 1. 2. 3. 4. 5. ATP surplus can be used for cellular activities like… Active Transport of materials Muscle Contraction Waste Removal Thought / Brain Activity Maintaining Homeostasis
