Microbiology BIOL2215 Study Guide Dr. Yoga Sundram Cellular Metabolism and Energy * Sun is the ultimate source of energy * When chemical bonds are made, energy is utilized: When they are broken energy is released. * Anabolism is building larger molecules from simple molecules: utilizes energy * Catabolism is breaking down larger molecules into smaller molecules: releases energy * Endergonic reaction: energy is absorbed * Exergonic reaction: energy is released * For energy to be formed, all nutrients need to go through a metabolic pathway called Kreb's cycle [ Citric Acid Cycle, Tricarboxylic Acid (TCA) cycle ] These nutrients enter the chemical pathway at different levels: Glucose at glycolysis level; Amino acid at pyruvic acid level and fatty acids at Acetyl coenzyme A levels Proteins Carbohydrates I Amino Acids t Deamination I Pyruvic Acid t Glucose Lipids t Fatty Acids t Beta Oxidation Glycolysis * i Pyruvic Acid I Acetyl Coenzyme A Aerobes use Oxygen molecules Acetyl Coenzyme A Electron Transport Chain t ATP Anaerobes use Oxygen containing ions Energy liberated Adenosine Triphosphate (ATP) 'Adenosine Diphosphate (ADP) Energy utilized C6H12O6 + 6O2 6CO2 + 6H2O + 38 ATP Microbiology BIOL2215 Study Guide Dr. Yoga Sundram Cellular Metabolism and Energy * Sun is the ultimate source of energy * When chemical bonds are made, energy is utilized: When they are broken energy is released. * Anabolism is building larger molecules from simple molecules: utilizes energy * Catabolism is breaking down larger molecules into smaller molecules: releases energy * Endergonic reaction: energy is absorbed * Exergonic reaction: energy is released * For energy to be formed, all nutrients need to go through a metabolic pathway called Kreb's cycle [ Citric Acid Cycle, Tricarboxylic Acid (TCA) cycle ] These nutrients enter the chemical pathway at different levels: Glucose at glycolysis level; Amino acid at pyruvic acid level and fatty acids at Acetyl coenzyme A levels Proteins Lipids i Fatty Acids Carbohydrates t Glucose i Glycolysis i Pyruvic Acid I Acetyl Coenzyme A + Arnino Acids t Deamination I Pyruvic Acid Aerobes use Oxygen molecules Beta Oxidation i Acetyl Coenzyme A Electron Transport Chain t ATP Anaerobes use Oxygen containing ions Energy liberated Adenosine Triphosphate (ATP) 'Adenosine Diphosphate (ADP) Energy utilized C6H12O6 + 6O2 6CO2 + 6H2O + 38 ATP
