Quizplus · Accepted Answer

The term "symmetry" describes the requirement for subunits to change conformation simultaneously in the concerted model of allosterism.

Answer: A
 The phrase "positively cooperative" describes the mechanism where substrate binding to one subunit of a protein enhances the ability of other subunits to bind substrate in the same protein. This is a hallmark of the concerted model of allosterism.

Answer: M
 The "sequential" model of allosterism describes a mechanism where subunits in a protein can change conformation and affect the binding properties of other subunits in a step-wise fashion. This is in contrast to the concerted model, where subunit conformational changes are required to occur simultaneously.
