Some hormones are transported in plasma bound to proteins.These proteins function to
A)Maintain a stable high concentration of the hormone in the plasma and reduce its clearance rate from plasma

D)Do all of these things
E)Do none of these things

Question

Quizplus · Accepted Answer

Proteins that bind to hormones in the plasma serve multiple functions. They maintain a stable high concentration of the hormone in the plasma by reducing its clearance rate. They also make the hormone more soluble in aqueous plasma. In some cases, binding proteins can reduce the binding of the hormone to its receptors, modulating its activity. Therefore, choice D, "Do all of these things," is the best answer.
