Why protein digesting enzymes are secreted in an inactive form in your body why it is not so incase of carbohydrate digesting and fat digesting enzymes?

Answer 1

Proteases are secreted in their inactive forms so as to prevent self-digestion and the destruction of the body's own cells. This is because all cells have proteins and hence are susceptible to the catabolic effects of proteases.

However, amylase is not secreted in an inactive form as we do not store starch in our cells, but rather, we store carbohydrates in the form of glycogen. Therefore amylase poses no risk to our cells.

Lipase-secreting cells also do not contain lipids and therefore lipase poses no threat to the body's own cells.

Answer 2

Protein digesting enzymes are secreted in an inactive form to prevent them from digesting proteins in the cells that produce them. Once released into the digestive tract, they are activated by a specific chemical or pH change. Carbohydrate and fat digesting enzymes are not typically secreted in an inactive form because they do not pose the same risk of digesting the cells that produce them.
