The histamine h1 receptor is one of several existing histamine g protein-coupled receptors. depending on many factors, including the type of receptor, histamine can trigger a variety of responses, including vasodilation, smooth muscle contraction, stimulation of gastric secretion, cardiac stimulation, and increased vascular permeability (causing runny nose and watery eyes). which of the following could account for the different cellular responses to histamine? select all that apply.
view available hint(s) o
a) the types of relay molecules within the cell
b) the enzyme that is activated by the g protein associated with the receptor o
c) the type of second messengers involved in the signal transduction pathway
d) the cell type in which the histamine receptor is located the type of signaling molecule

All statements are true.

Explanation:

Histamine is the chemicals released during the inflammatory and allergic reaction of the body. Histamine causes the capillaries dilation and the smooth muscle contraction.

Histamine works as the G protein coupled receptor. It depends on the tupe of molecules associated with it. The molecule that are activated by the enzyme is linked with O receptor. Histamine receptor and its binding with the molecule acts as the signalling molecule. The secondary messengers like cAMP, cGMP are also involved in the signal transduction pathway.

Thus, all statements are apply.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

is this a question? wassup
