Digestive Enzyme

The digestive system is a series of organs either joined to fillher from the lecture to anus. Digestion is a bodily reduce that breaks fringe vanquish food in several processes. Our bodies need square(a) types of fuel to function properly and its is all found in food in forms of molecules, it is necessary for these large molecules to be befuddled down because they cannot be digested as they are. Starch, Proteins and lusciouss are large molecules which cant hook on through cell walls into the blood. The three proteins are scattered down into sugars, amino panes and glycerol or plump outty acids which are busted down by enzymes and then used to build and protect new cells and create energy. An enzyme is k outrightn as a gas because it is not consumed or used up in reactions. Digestion begins in the mouth, when we chew. The food is swallowed then travels down the oesophagus which is connected to the patronize. The take has three mechanical tasks to do. Firstly Muscles in the raise disencumber and allow large amounts of food to be stored, secondly the stomach releases the protease enzyme (pepsin) which breaks down proteins into abjecter pieces called peptides. Hydrochloric acid is also present. This kills whatsoever bacteria. The enzymes in the stomach work best in these acid conditions. thirdly the food is emptied into the crushed gut .

When the food enters the itsy-bitsy intestine it has been partially broken down by the mouth and the stomach. In the small intestine digestion of the food is completed and the molecules that sacrifice been antecedently broken down into soluble molecules are now able to dif! fuse into the blood stream by wide stir up uptake. The walls of the small intestine secrete protease, carbohydrase and lipase. The pancreas also secretes these three enzymes into the small intestine. Another organ which is used in this last partition off process is the gall bladder. It produces bile which helps break down fat molecules, it is produced in the liver which helps emulsifies fats and neutralises the stomach acid because...If you want to get a full essay, order it on our website: OrderCustomPaper.com
