Document Summary
Body cant produce, must be acquired in diet: metabolic rates (amount of energy used per unit of time) kcal used to measure metabolic rate. Basal metabolic rate (bmr) - at rest, no digestion. Standard metabolic rate (smr) - at rest, at certain temperature. Malnourishment - not getting enough nutrients (right vitamins) Undernourishment & over nourishment: 20 aa in animals, 8 from diet. In right proportions, those needs can be met: most common is protein deficiency. Vegetarian diets lack certain aa because plant proteins are incomplete: vitamins. Different for every organism (13 essential in humans) Water soluble excess = not a big deal, excreted in urine. Deficiencies: vitamin c (ascorbic acid) scurvy. 43. 2 capturing food: structure & function of mouthparts: strategies. Mouthparts have diversified in response to natural selection. 43. 3 how are nutrients digested and absorbed: incomplete digestive tract, complete digestive tract. Gastric ceca (blind pouch) - storage, flora: processing, overview of digestive process.
