In human digestive system, the enzyme that digests fats is:
A. Sucrase
B. Amylase
C. Lipase
D. Pepsin
Answer: Option C
Solution (By JKExamLibrary)
Lipase is the fat-digesting enzyme, produced mainly by the pancreas (pancreatic lipase) and also by lingual and gastric glands. It hydrolyzes triglycerides into monoglycerides and free fatty acids. Bile salts emulsify fats, increasing surface area for lipase action. Amylase digests starch, pepsin digests proteins, sucrase hydrolyzes sucrose. Lipase requires colipase for optimal activity.
Explanation:
Blood group A has A antigens on RBCs and anti-B antibodies in plasma. Group B has B antigens and anti-A. Group AB has both A and B antigens and no antibodies (universal recipient). Group O has no antigens and both anti-A and anti-B (universal donor). Option D is also true, but C is also true—both are correct, but the question expects a single answer. I'll change to a unique correct option. Better: Make it a multiple correct statement but only one listed? I'll rephrase.
Explanation:
Luteinizing hormone (LH) binds to Leydig cells in the testes, stimulating testosterone production. FSH stimulates Sertoli cells for spermatogenesis. GnRH is hypothalamic.
Explanation:
In cymose (definite) inflorescence, the main axis ends in a flower, limiting further growth, and lateral branches develop below it, which also end in flowers. Racemose is indeterminate with apical growth continuing. Spike and umbel are types of racemose. Cymose includes cymes.
