Enzymes are organic catalysts and very specific as to
which substrates they interact with. They are proteins with a specific shape. Their
active site is where they bind to a specific substrate and catalyze a reaction. A
quantitative experiment that can be conducted is the influence of temperature on the
action of an enzyme. Catalase, an enzyme present in cells,  causes hydrogen peroxide, a
toxic substrate to break down into water and oxygen. Therefore, if small pieces of liver
which naturally contain the enzyme catalase, were placed in three different test
tubes; one containing room temperature water, one with ice water and one with boiling
water, and the same amount of hydrogen peroxide was added to each test-tube, one could
measure the amount of bubbling in each test tube and the length of time, the bubbles
were produced and place these numbers in a data table. This is quantitative data. If the
catalase enzyme is affected by temperature, there might be less or no bubbling,
indicating that hydrogen peroxide was not breaking down into water and oxygen gas and
the enzyme couldn't work. Denaturation affects an enzymes shape and active site.
Temperature extremes can cause an enzyme to become denatured and thus not be able to
catalyze a reaction.
