... c) Full activity of E1 is observed at 37oC and a pH of 7.4. You isolate the active form of E1, subject it to a pH of 2.0 and show that it cannot bind to the substrate. You revert to pH 7.4 and see that the enzyme does not resume its function. Explain why is this so. Altering the pH from 7.4 to 2.0 d ...
