Which of the following would cause a protein response rate to be maximal?

A) The protein binding sites are saturated.

B) The protein is denatured.

C) There are too few ligand molecules

D) The protein has been down-regulated.

Answer

The protein response rate is maximal when the protein binding sites are saturated (option A).

Denaturation and down regulation result in decrease in protein response. When there are too few ligand molecules, some of the protein binding sites are unoccupied resulting in submaximal response.
