Best Answer

The cells of the stomach make an pro-enzyme called pepsinogeen. When pepsinogeen is secreted in the acidic (pH 2-3) environment of the stomach it transforms into pepsine, an enzyme wich breaks down proteins. If pepsine was made directly in the cells, it would destroy the cell before it would secreted in the stomach.
