Фрагмент работы

An enzyme is a protein which functions as an organic catalyst, which allows a particular reaction to occur without using itself up in the process. Without enzymes, most reactions in a cell would not occur. Enzymes function best in an acidic environment as do catalase, however the correct concentration of an acidic solution is needed to ensure the most efficient reaction. Placing a catalase enzyme into a solution which is slightly acidic (less than pH 7) produces the best catalytic reaction including foaming and bubbling. There are many different types of enzymes, and all of which operate at peak efficiency in concentrations of acids and/or bases (different pH levels). Some enzymes, like the ones contained in blood cells work best in a neutral environment ( pH 7), but others such as stomach enzymes would work best in a very acidic environment ( pH 1-2). …
