Answer:
-Histamine binds extracellularly to the H1 receptor.
-When histamine binds to the H1 receptor. the receptor undergoes a conformation change and binds the inactive G protein.
-Once the G protein is active, it binds to the enzyme phospholipase C, activating it.
-Histamine is likely hydrophilic.
When histamine encounters a target cell, it binds extracellularly to the H1 receptor, causing a change in the shape of the receptor. This change in shape allows the G protein to bind to the H1 receptor, causing a GTP molecule to displace a GDP molecule and activating the G protein. The active G protein dissociates from the H1 receptor and binds to the enzyme phospholipase C, activating it. The active phospholipase C triggers a cellular response. The G protein then functions as a GTPase and hydrolyzes the GTP to GDP. The G protein dissociates from the enzyme and is inactive again and ready for reuse.

Explanation:
What do low levels mean? Low TSH levels indicate hyperthyroidism. This is also known as an overactive thyroid. If the thyroid gland is secreting levels of hormones that are too high, the pituitary gland produces less TSH

Answer:
<h2>Vegetarians, especially vegans, need to consume adequate amounts of the essential amino acids by choosing complementary proteins and eating plant sources of complete protein like soy and quinoa.</h2>
Explanation:
Vegetarian diet does not contain all the essential amino acids. Amino acids are of two types, essential and non- essential amino acids. The essential amino acids are not synthesized by our body so we must have to take these essential amino acids through food. So vegetarians, especially vegans, need to consume adequate amounts of the essential amino acids by choosing complementary proteins and eating plant sources of complete protein like soy and quinoa.
