SpletThe optimum pH for an enzyme depends on where it normally works. For example, enzymes in the small intestine have an optimum pH of about 7.5, but stomach enzymes have an optimum pH of about 2. SpletSeveral theories have been proposed to explain the mode of enzyme action. (1) General Theory of Enzyme action (Enzyme – substrate complex theory): Victor Heneri (1903) first proposed that the enzyme (E) combines with substrate (S) to form enzyme-substrate (ES) complex as a necessary step in enzyme catalysis.
