A signal transmitted via phosphorylation of a series of proteins is generally associated with which of the following events?
A) conformational changes to each protein in the series
B) binding of a hormone to an intracellular receptor
C) activation of a ligand-gated ion channel
D) production of ATP in the process of signal transduction

Question

Quizplus · Accepted Answer

Phosphorylation of proteins in a signaling pathway typically leads to conformational changes in each protein, which is essential for the transmission of the signal through the pathway. This process does not directly involve hormone binding to intracellular receptors, activation of ligand-gated ion channels, or the production of ATP during signal transduction.
