What is the correct option for the hormone whose mechanism of action is shown in the given figure?
This hormone will most likely be synthesized by the neural cells of the hypothalamus
This hormone cannot be thyroxin or triiodothyronine
This hormone can be a derivative of cholesterol
This hormone will have an almost instantaneous onset of action
Many hormones are derived from cholesterol, which is a type of lipid or fat molecule. Cholesterol is a precursor to a variety of hormones, including steroid hormones and we know lipid or fat-soluble hormones act through intracellular receptors.
Therefore, the answer is option 3.
