Macrophage. They change their cellular shape to surround an invader and take it through the process of phagocytosis. It recognizes if the cell is ‘self’ or ‘not self’‚ by the protein make-up of the cell. The ‘not self’ cells are engulfed and then the enzymes within the phagocytes called lysosomes then digest the pathogens. Phagocytes can ingest pathogens in the blood but also within body tissue as they can pass through the pores of capillaries and into these tissues. 6.3.6 Antibodies are protein molecules

What is Enzyme? Enzymes are protein that acts as speed up reactions and break down molecules in our body. However‚ different enzymes only work on certain types of molecules. Enzymes can accelerate the reactions by more than one million times.(3) In our human body‚ there are a total about forty thousand types of enzymes and each catalyzes different kind of molecule.(3) The molecules that enzymes help to accelerate is called substrates‚ and when enzyme is combined together with the substrate‚ it

it’s lowest to do so. However‚ in cold solutions the starch will take longer as it will in temperatures beyond 40 degrees. Once it reaches this point‚ the break down will either take a very long period of time or have no reaction at all as enzymes are denatured at a certain point.

amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which is the bodies normal pH. The pH affects the charge of the amino acid at the active site. PH changes affect the structure of an enzyme molecule and therefore affect its ability
