The Action of a Hormone on a Target Cell Involves

Question

The action of a hormone on a target cell involves effects on
A) receptor proteins.
B) nonreceptor proteins.
C) lipids.
D) receptor and nonreceptor proteins.
E) receptor proteins and lipids.

Accepted Answer

Hormones can affect target cells by interacting with both receptor and nonreceptor proteins. Receptor proteins on the cell surface or inside the cell bind to hormones, initiating a cascade of cellular responses. Nonreceptor proteins can be involved in these cascades or in the processing and transport of hormones within the cell.
