The organelle that contains enzymes for intracellular digestion is the: MCQ with Answer and Explanation

Explanation:
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:
Glucagon-like Peptide-1 (GLP-1) is a powerful incretin hormone secreted by the L cells of the distal small intestine (ileum) and colon in response to food ingestion. Its primary functions are highly beneficial for glucose homeostasis: it stimulates insulin secretion from the pancreas in a glucose-dependent manner (only when blood glucose is high), inhibits glucagon secretion, slows down gastric emptying (allowing more time for nutrient absorption), and acts on the brain to promote satiety and reduce food intake. GLP-1 analogs (like exenatide) are used as drugs to treat type 2 diabetes.

Explanation:
Vitamin B₁₂ (cobalamin) is required for DNA synthesis and RBC maturation. Deficiency causes pernicious anemia. It also maintains myelin sheath.
