		Gastric glands produce both endocrine and exocrine secretions.
		The secondary structure of proteins is stabilized by ionic interactions between neighboring amino acids.
		Substances that have a bitter taste activate a signaling pathway in a given taste cell that leads to the release of ATP from that taste cell.
		The stomach is an organ that functions primarily in the storage and initial chemical and mechanical breakdown of food, but can also be a site of absorption for hydrophobic molecules such as ethanol.
		Chylomicrons synthesized by intestinal cells cannot be found in the hepatic portal vein.

Answer 1

1. Gastric glands:-present in the lamina propria of the mucous membrane and they open into the bases of the gastric pits formed by the epithelium. The various cells of the glands secrete mucus, pepsinogen, hydrochloric acid, intrinsic factor, gastrin, and bicarbonate. The secretions is  exocrine which make up the gastric juice. The products of the endocrine cells are secreted directly into the bloodstream and are not a part of the gastric juice. so we can conclude that the gastric gland is only exocrine gland and not endocrine glnd . Therefore this sentence is incorrect.
