Metabolism Review The purpose of this experiment was to investigate energy metabolism through the measurement of oxygen consumption and carbon dioxide expiration. By doing so, this provided an estimate as to how much energy was used during various activities. Introduction o Metabolism - the sum total of all chemical reactions in the body Divided into two categories: Anabolism - the storage of energy by creating large molecules with high energy bonds Catabolism - the breaking down of these molecules to release energy to be used Affected by several factors: gender, body consumption, genetics, food consumption, physical activity, sleep, age, and hormones o Metabolic processes – glucose can be oxidized for energy inside cells and generates CO 2 as waste, or can be converted to glycogen for storage in the liver or skeletal muscle o Glycogenolysis – if glucose levels decrease, glycogen can be broken down Measuring Metabolism o Measured in Calories One calorie (or kcal) is the amount of energy needed to increase
