Question

When insulin binds to its receptor, the complex is endocytosed into the cell. This is an example of ______ in response to hormone signaling.

cAMP activation
generating an intracellular receptor
activation of a hormone response element
receptor down-regulation

Answer 1

receptor down-regulation

Step-by-step explanation:

Downregulation is a control mechanism by which a cell decreases the amount of a cellular component, such as RNA or protein, in response to an external variable. In contrast, a reactive increase of a cellular component is called upregulation. An example of downregulation occurs when insulin binds to its receptor and the complex is endocyted in the cell in response to hormonal signaling.
