Which of the following correctly describes the mechanism of nutrient sensing via chemoreceptors and its integration into the gut-to-brain axis?

Question

Accepted Answer

Ingested nutrients like glucose and fatty acids activate specific G-protein coupled receptors (GPCRs) on enteroendocrine cells, which triggers both the release of satiety gut peptides and the activation of vagal afferent signaling.

Answer

Chemoreceptors are specialised endings known as Intraganglionic Laminar Endings (IGLEs) that respond to the chemical acidity of the stomach to trigger meal initiation.

Answer

The activation of chemoreceptors by Long-Chain Fatty Acids (LCFAs) leads to a paradoxical increase in acylated ghrelin levels to ensure neutral energy balance.

Answer

Nutrient sensing occurs exclusively in the mucosal layer of the stomach, where chemoreceptors detect the volume of a meal to inhibit the firing of the Nucleus of the Solitary Tract (NTS).
