The answer to this question is A
In the above case, as a knowledgeable EMT, my best response would be TO CONVINCE THE PERSON TO GET EXAMINED AS FALLING FROM SUCH A HEIGHT MIGHT INJURE THE INTERNAL ORGANS. EXAMINATION OF THE INTERNAL ORGANS WOULD GIVE DETAILED STRUCTURE AND STATUS OF THE OVERALL BODY PARTS.
It will eventually start to boil if it gets hot enough and turn into water vapor or steam.
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.
