Answer:
they are able to perform a specialized function in the body
<span>There are diagnostic analysis used to
identify patients with heart failure. One of which is echocardiogram and chest
x-ray that rely on imaging of the heart to assess its structure and function. Another
ancillary test to detect abnormalities that may point to heart failure is the B
type Natriuretic peptide, the detection of this serum levels is known to rise
in the heart failure syndrome.</span>
Enzymes are proteins that are biological catalysts
They reduce the activation energy required for a reaction to occur and thus speed up a reaction
Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)
They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's
They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.
They aren't used in the reaction so they're re-usable.
If it isn't one of these then it is not one of the properties of enzymes
