One of the major categories of receptors in the plasma membrane reacts by forming dimmers, adding phosphate groups, then activating relay proteins. Which type does this?
A)G protein-linked receptor
B)ligand-gated ion channels
C)steroid receptors
D)receptor tyrosine kinases

Question

Quizplus · Accepted Answer

Receptor tyrosine kinases form dimmers when activated by ligand binding which allows them to add phosphate groups to each other via autophosphorylation, leading to the activation of downstream relay proteins. G protein-linked receptors, ligand-gated ion channels, and steroid receptors all have different mechanisms of signal transduction in which they do not necessarily form dimers and activate relay proteins through autophosphorylation.
