Contrary to legend, camels do not store water in their humps, which actually consist of large fat deposits. How can these fat deposits serve as a source of water? Calculate the amount of water (in liters) that a camel can produce from 1.0 kg of fat. Assume for simplicity that the fat consists entirely of tripalmitoylglycerol.

A) Oxidation of fats releases metabolic water

B) L of water per kg of tripalmitoylglycerol

Explanation:

A)During the oxidation of organic substances (fats) releases metabolic water along with release of energy

For example –  

 Oxidation of one mole of Palmitic acid (C16H32O7) acid releases 146 mole of H2O. In Tripalmitoylglycerol (fat C51H98O6) , there are 3 palmitic acid residues connected to glycerol molecule via ester bonds.

Oxidation of Palmitoyl CoA:

almitoyl-CoA + 23O2 + 108Pi + 108 ADP => 88nCoA + 108 ATP + 16CO2 + 23 H2O

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
