BIOL 003 Lecture Notes - Lecture 14: Basal Metabolic Rate, Trypsin, Pepsin
Document Summary
Proteins amino acids (from pepsin, trypsin, peptidases) Not a major source of energy amino acids rather be used to form our own body"s proteins. Amino acids pyruvic acid or acetyl-coa citric acid cycle electron transport chain. Remove amine from amino acid (-nh2) ammonia + -keto acid + nadh. Liver: ammonia urea excreted through urine. Nutrients & glucose from digested food being absorbed. Glucose circulation used by cells. Excess glucose stored as glycogen & fat: postabsorptive state. At least 4 hrs after last meal. Glucose absorption from food ceases must now rely on stored glucose. 4 hrs) and eventually fat stores are used. Metabolic rate: total amount of energy produced and used by body p/unit time. Basal metabolic rate: energy required to keep body functional at rest. We keep body temperature constant at 37oc. Metabolism, exercise & environment can influence body temp. Free energy: total energy that could be liberated with 100% catabolism of food.
