Answer 1

Answer 15:

Hunger or appetite is a consequence of not eatng for a cetrain period of time that stimulates the sensory system and as a result there is churning or contraction in the empty stomach.

Correct options is d)Ghrelin

Ghrelin, which is often called as hunger hormone is secreted by the enteroendocrine cell that belongs to gastrointestinal tract. There is high concentration of Ghrelin in blood at the time of hunger and lowers down after the meal. It could help in intake of food by increasing gastic acid secretion and gastric motility. It is responsible for activation of neuropeptide Y that initiates appetite.

Pepsin has a role in digestion especially in protein digestion.

Gastrin hormone is responsible for the release of gastric acid from the parietal cells.

Cholesystokinin hormone is responsible for the bile production.
