Protein kinase receptors phosphorylate themselves and/or other proteins when activated, resulting in a(n)
A) change in shape and function of the proteins.
B) increase in production of ATP.
C) change in the dissociation constant.
D) decrease in ligand-receptor binding.
E) inhibition of further transduction of the signal.

Question

Quizplus · Accepted Answer

Protein kinase receptors are involved in signal transduction pathways, where they activate downstream effector proteins through the process of phosphorylation. Phosphorylation of proteins can change their shape and function, leading to a cellular response. Therefore, choice A is the best answer.
