BIOL 3070 Lecture Notes - Lecture 23: Catabolism, Carbohydrate Metabolism, Indirect Calorimetry
Document Summary
Because these rxns are not 100% efficient, some heat released released (energy) some chemical energy lost through fecal/urine waste. Main determinant of how much food an animal needs (can be important for estimating how much food you"ll need to sustain a mouse vs an elephant) Measured in calories/joules (amount of heat required to raise 1g of water by. 1degrees celsius ie. from 14. 5 to 15. 5 degrees celsius) kcalories or kjoules/unit of time (to measure the rate!) Apply bmr to endothermic animals for ectothermic animals, use standard metabolic rate (resting and fasting metabolism measured at specific temp ectotherm"s metabolism depends on tambient!) Co2/rate o2) this depends on the type of food the animal is eating (carbohydrate diff. from lipid diff. from protein) respiratory exchange close to rq. Absorptive (fed) state: when nutrient molecules are ingested and etner the blood, when these complex macromolecules broken down into aa or glucose, used for catabolic processes (net synth. of proteins or carbohydrates/fat)
