LIFESCI 15 Lecture Notes - Lecture 11: Basal Metabolic Rate, Plants And Animals, Chyme
Document Summary
Omnivores eat plants & animals (humans, cockroaches) But the processing and deriving of energy from food is always the same. The kilocalorie 1000 calories (energy req"d to raise 1g h2o by 1c = 1 calorie) Basal metabolic rate (bmr) energy needed to maintain life without activity. Male 1700 kcal/d (~ 75 watt lightbulb for 24h) 5g x 35 cal x 24 hrs = 4200 cal = 4. 2kcal/day *double bmr* Basal metabolic rate is the energy expenditure necessary to keep a resting animal alive. Humans aid the process by: cook food in high temps, marinate in harsh acids (lime juice/vinegar) Basic substances helps neutralizes the acid when you have indigestion and relieve heart burns. Long term: not good because taking a lot of antacids makes your stomach less acidic and less effective in digesting your food. Two aa"s stuck together (technically a protein) similar to monosaccharides (sugar) The bonds that hold them together are sensitive to heat.
