Question 1

Which of the following mechanisms best describes the action of statin drugs in lowering cholesterol levels?

Accepted Answer

B. Inhibiting HMG-CoA reductase enzyme — Statins, such as atorvastatin and simvastatin, are competitive inhibitors of HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis in the liver. This inhibition leads to a decrease in endogenous cholesterol production, which in turn upregulates LDL receptors on hepatocytes, increasing LDL clearance from the blood. Increasing bile acid excretion is the mechanism of bile acid sequestrants, activating lipoprotein lipase is primarily for fibrates, and blocking cholesterol absorption is for ezetimibe.

A. Increasing bile acid excretion in the feces

Answer

C. Activating lipoprotein lipase to break down triglycerides

Question 2

A State government proposes a legislative bill that aims to provide free and compulsory education for all children up to the age of fourteen years, along with promoting the educational and economic interests of the weaker sections of the people. Which parts of the Indian Constitution primarily guide the State's action in proposing such a bill?

Accepted Answer

C. Fundamental Rights and Directive Principles of State Policy — The proposed bill is guided by both Fundamental Rights and Directive Principles of State Policy. Article 21A (a Fundamental Right) mandates free and compulsory education for children aged six to fourteen, which was introduced to fulfill the spirit of Article 45 (a DPSP). Additionally, promoting the educational and economic interests of weaker sections is a direct directive under Article 46, which is also part of the DPSPs.
