The 'Hormone Resistin' is secreted primarily by adipose tissue in humans (and by macrophages in rodents). Its primary function is to: MCQ with Answer and Explanation

The 'Hormone Resistin' is secreted primarily by adipose tissue in humans (and by macrophages in rodents). Its primary function is to:
A. Antagonize insulin action, promoting insulin resistance and increasing hepatic glucose production
B. Stimulate fat storage
C. Enhance insulin sensitivity
D. Inhibit appetite
Answer: Option A
Solution (By JKExamLibrary)
Resistin is a cysteine-rich peptide hormone secreted primarily by adipose tissue in humans (though in rodents, it is mainly secreted by macrophages). Its name is derived from its proposed role in 'resistance' to insulin. Its primary function is to antagonize the action of insulin, thereby promoting insulin resistance. It does this by increasing hepatic glucose production (gluconeogenesis) and impairing glucose uptake by muscle and adipose tissue. Elevated levels of resistin are associated with obesity and type 2 diabetes, linking adiposity to insulin resistance.

Question #1
Which of the following is a saturated fatty acid?
A. Palmitic acid
B. Oleic acid
C. Linolenic acid
D. Linoleic acid

Correct Answer: Option A


Explanation:
Saturated fatty acids have no double bonds between the carbon atoms in their hydrocarbon chain, making them 'saturated' with hydrogen atoms. They are typically solid at room temperature. Palmitic acid and stearic acid are common saturated fats. Oleic, linoleic, and linolenic acids are unsaturated fatty acids, containing one or more double bonds.

Question #2
Which of the following statements about RNA is correct?
A. tRNA is the main component of ribosomes.
B. It is usually double-stranded.
C. It contains the base thymine.
D. mRNA carries the genetic message from DNA to ribosomes.

Correct Answer: Option D


Explanation:
mRNA is the template for translation. RNA is typically single-stranded, contains uracil, rRNA forms ribosome structure.

Question #3
The mineral that is essential for the action of insulin and is a component of many enzymes is:
A. Zinc
B. Calcium
C. Sodium
D. Magnesium

Correct Answer: Option A


Explanation:
Zinc is required for the synthesis, storage (as hexamers), and secretion of insulin in pancreatic beta cells. It also acts as a cofactor for numerous enzymes like carbonic anhydrase and DNA polymerases. Calcium is for bones/signaling, magnesium for ATP and chlorophyll, sodium for nerve impulses.
