Document Summary
Metabolic rate-total energy expenditure per unit time. Basal metabolic rate-basic metabolic cost of living (complete degree celsius physical, mental rest, thermoneutral environment, post- absorptive state (no digestion): factors impacting metabolic rate: Sleep, age, gender, fasting, height, weight; based on fat-free. Endocrine determinants of basal metabolic rate: mass: 1. Increases the insertion of na/k atpase pumps in cell membranes throughout body increase atp consumption. Also, uncoupling protein inserts h ion channels in membrane, creating a leaky channel, which gets released as heat energy; the more h released through leak channels, the more heat released, the high the bmr is: 2. Once you release glucose/fa into blood, if you don"t use those energy stores, you put them back into storage, which takes energy: 3. Extra used for nutrient absorption and digestion. Fat uses the least amount of energy because it diffuses passively into the epithelial cells, and protein is the highest: 4.
