Rennin is from a cow and that is what we used. Rennin is an enzyme and it is affected by temperature. Theory The lock and key theory is simply a way of describing how specific an enzyme is for its substrate. Just like a lock requires a specifically shaped key for it to work so does an enzyme. Each enzyme is a protein which is a polypeptide chain folded into a complex 3 dimensional structure.
