The 'Hormone Amylin' (Islet Amyloid Polypeptide) is co-secreted with insulin by the beta cells of the pancreas. Its primary functions include: MCQ with Answer and Explanation

The 'Hormone Amylin' (Islet Amyloid Polypeptide) is co-secreted with insulin by the beta cells of the pancreas. Its primary functions include:
A. Slowing gastric emptying, suppressing glucagon secretion, and promoting satiety
B. Increasing gastric acid secretion
C. Stimulating intestinal motility
D. Stimulating insulin release
Answer: Option A
Solution (By JKExamLibrary)
Amylin, also known as Islet Amyloid Polypeptide (IAPP), is a 37-amino acid peptide hormone that is co-secreted with insulin from the pancreatic beta cells in response to meals (in a ratio of about 1:100 to insulin). Its primary functions are to complement the actions of insulin in regulating postprandial (after-meal) glucose levels. It does this by slowing gastric emptying (preventing a rapid spike in blood glucose), suppressing the secretion of glucagon (preventing the liver from releasing glucose), and acting on the brain to promote satiety and reduce food intake.

Question #1
The valve between the left atrium and left ventricle is the:
A. Pulmonary semilunar valve
B. Bicuspid (mitral) valve
C. Tricuspid valve
D. Aortic semilunar valve

Correct Answer: Option B


Explanation:
The bicuspid valve (mitral valve) has two cusps and is located between the left atrium and left ventricle, preventing backflow during ventricular systole. The tricuspid valve is on the right side. Semilunar valves are at the exits of the aorta and pulmonary artery. Mitral valve prolapse is a common condition.

Question #2
The first successfully cloned mammal, Dolly the sheep, was produced using:
A. Somatic cell nuclear transfer
B. Recombinant DNA technology
C. Gene therapy
D. Artificial insemination

Correct Answer: Option A


Explanation:
Dolly (1996) was created by somatic cell nuclear transfer (SCNT), where the nucleus from an adult somatic cell (udder) was transferred into an enucleated egg cell, which was then implanted in a surrogate. This proved that differentiated somatic cells can be reprogrammed to totipotency. She was the first mammal cloned from an adult cell.

Question #3
Tocopherol is the chemical name of which vitamin?
A. Vitamin E
B. Vitamin K
C. Vitamin B₁₂
D. Vitamin A

Correct Answer: Option A


Explanation:
Vitamin E is a group of tocopherols and tocotrienols, acting as fat-soluble antioxidants. They protect cell membranes from oxidative damage. Deficiency is rare but can cause hemolytic anemia and neurological problems.
