Document Summary
The sum of all chemical reactions involved in obtaining and utilizing food energy. Calorie (cal): measure of heat: kcal = 1000 calories = 1 calorie = 1 cal. 1 calorie: 1 kcal = 4. 18 kj (kilojoules, energy required to raise the temperature of 1 kg (1l) of water by 1 c. Positive energy balance: weight gain / obesity, infertility, cardiovascular disease, insulin resistance. Negative energy balance: weight loss, infection (*bmi 30, or about 30 lbs. overweight for 5"4 person) Compared heat produced by a guinea pig with the production guinea pig with the production of co2 equivalent to ice that melts) Co2 formed from the reaction between oxygen and organic matter: justin liebig recognized that protein cho and fats are protein, cho, and fats are oxidized, max rubner measured energy values of certain foods to determine caloric values. We consume macronutrients, including proteins/amino acids, fats and carbohydrates (cho) for essential roles in building cells and tissues g y.
