You are working with a team of scientists who are investigating the biochemical control system involved in how animals digest fats in their meals. You have evidence that there must be a signal molecule involved that is released soon after the fats are consumed. When this signal molecule is present it triggers activation of appropriate digestive enzymes and cellular uptake transporters until the meal has been fully digested. Based on this information, what type of signal molecule would you predict is involved in this process

The question is incomplete as it does not have the options which are:

A. hydrophobic hormone

B. peptide or amine hormone

C. cAMP

D. steroid hormone

E. protein kinase

Answer:

B. peptide or amine hormone

Explanation:

The fats are digested by the enzymes' lipases in the small intestine in humans.

Once the fats are digested, the signal molecules called the peptide hormone or amine hormone which are synthesized by the modification in the amino acid are released.

This hormone is known as somatostatin which is produced by the delta cells after the fat enters the duodenum. The somatostatin inhibits the synthesis of the pepsin, gastrin, insulin, and lipase. Since the somatostatin is a peptide hormone, therefore, is the correct answer.
