Some people do not make enough of an enzyme in the blood.

All reactions in the body are the work of enzymes.

You may also have blood tests to see if your levels of certain enzymes are higher than normal.

But because they actually get a great deal less of the enzyme, the fertility window is only a few days long for them.

The specific activity of an enzyme is another common unit.

The activity of the enzyme is controlled in several ways.

Therefore, it requires 40 to 100 times more of the enzyme to be present in its production.

Organisms are not limited to having one class of enzymes.
