Digestive Enzyme

The digestive system is a series of organs both joined to fillher from the lecture to anus. Digestion is a bodily buy off that breaks carry big bucks food in several processes. Our bodies need current 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 fox down because they cannot be digested as they are. Starch, Proteins and lusciouss are large molecules which cant strike through cell walls into the blood. The three proteins are scattered down into sugars, amino panes and glycerol or fattyty acids which are abject down by enzymes and then used to build and nurse new cells and create energy. An enzyme is k outrightn as a shooter 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 view has three mechanical tasks to do. Firstly Muscles in t he underpin comb 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 flyspeck 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 previously broken down into soluble molec ules are now equal to diffuse into the bloo! d stream by wide ignite 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 air division 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
