ACS Biochemistry Exam Questions With Complete Solutions Metabolism (catabolism and anabolism) - ANSWERS Metabolism: sum of total chemical reactions in an organism, also the method by which cells extract and use energy from their environment. Catabolism: The process by which stored nutrients and ingested foods are converted to a usable form of energy. It produces simple products CO2, H2O, NH3, and building blocks such as sugars and fats that are used in anabolism. Anabolism: t...

Bohr effect - a decrease in the amount of oxygen associated with hemoglobin and other respiratory compounds in response to a lowered blood pH resulting from an increased concentration of carbon dioxide in the blood. Cooperativity - Structural communication between various subunits of hemoglobin, a result of its quaternary structure. Deoxyhemoglobin - The form of hemoglobin without oxygen. Oxyhemoglobin - Combination of hemoglobin with oxygen
