Which one of the following pairs of the kind of cells and their secretion is correctly matched?
Options
- AOxyntic cells --- a secretion with pH between 2.0 and 3.0
- BAlpha cells of islets of Langerhans --secretion that decreases blood sugar level
- CKupffer cells - a digestive enzyme that hydrolyses nucleic acids
- DSebaceous glands --- a secretion that evaporates for cooling
Correct answer
D. Sebaceous glands --- a secretion that evaporates for cooling
Step-by-step solution
Oxyntic (or parietal) cell is present in the wall of the stomach that produce HCl which forms the part of gastric juice. Oxyntic cell also produce intrinsic factor which is involved in the absorption of vitamin B ₁₂ in the small intestine. The pH of gastric acid is 2-3 in the stomach of the lumen. The acidity being maintained by the proton pump, a H ⁺ / K ⁺ ATPase. Alpha cell of islets of langerhans secrete glucagon hormone which raises blood glucose level by stimulating liver to convert glycogen to glucose and by
