A) Oxyntic cells - A secretion with pH between 2.0 and 3.0.
B) Alpha cells of Islets of Langerhans - Secretion that decreases blood sugar level.
C) Kupffer cells - A digestive enzyme that hydrolysis nucleic acids.
D) Sebaceous glands - A digestive enzyme that hydrolysis nucleic acids
Correct Answer: A
Solution :
[a] Oxyntic cells or Parietal cells, are the stomach epithelium cells that secrete gastric acid intrinsic factor. These cells secrete hydrochloric acid (HCl) which makes the gastric juice acidic (pH =2.0-3.0). Alpha cells of islets of Langerhans secretes glucagon hormone which increase the glucose level in the blood by converting glycogen to glucose in liver cells. Kupffer's cells are specialized cells in the liver that destroy bacteria, foreign proteins, and worn-out blood cells. Sebaceous glands and microscopic glands in the skin that secrete an oily/waxy matter (called sebum) to lubricate the skin and hair of mammals.
