Select all the true statements about sequential versus concerted models of allostery. Group of answer choices A. In sequential allostery, binding of the substrate on one end of an enzyme causes a conformational change on the other end which propagates to another enzyme and enables easier binding of a second substrate to the second enzyme B. No conformational changes occur in either model C. In concerted allostery, the two forms of the enzyme exist in equilibrium because of a conformational change independent of substrate binding D. In concerted allostery, binding of the substrate to one of the forms is favorable (but not to the other) and binding of the second substrate is enhanced on the favorable form
