  • diffuses through the mitochondrial and cell membranes by lipid diffusion, out into the tissue fluid and into the blood, where it is carried to the lungs for removal. The hydrogen is taken up by NAD again.
  • Carbohydrates Lipids( Proteins Of the 106 elements known to man very few are required to form the most common compounds of carbohydrates, lipids and proteins; These can be summarised as follows:
  • it cannot digest protein, carbohydrates or lipids. this is because each type of food substance has a particular shape. since enzymes can only function if they have a particular shape, the type of substance
  • Bile contains bile salts to aid lipid digestion, and the alkali sodium hydrogen carbonate to neutralise the stomach acid. Without this, the pancreatic enzymes would not work. The bile duct and the pancreatic
