Document Summary
Carbohydrates provide atp stored as glycogen. Acid formation of connective tissues prevent oxidation of cellular constituents. It"s hard to o(cid:448)erdose o(cid:374) (cid:449)ater-soluble vitamins because once body reaches maximal capacity the excess vitamins would just be excreted in urine. Saprobes feed on dead organic matters. Detritovores waste products of other organisms. Filter feeders trap tiny particles or organisms suspended in water e. g. plankton. Energy units calories the amount of energy burnt to raise the temperature of 1gm of water by 1 c. Under when body is deficient in nutrition/food, the body would break down sugar, and then lipids, and lastly proteins. Over leptin is involved in long-ter(cid:373) regulatio(cid:374) of (cid:271)ody (cid:449)eight. It circulates in the blood and acts on hypothalamus, skeletal muscle and liver to send signals when full. Causes of overweight: mutation on both ob genes would block the leptin production, hence no sig(cid:374)als (cid:449)ould re(cid:373)i(cid:374)d the (cid:271)ody if (cid:449)hat"s e(cid:374)ough, reduced sensitivity to leptin and therefore leptin is ineffective.
