Consider the following statements regarding Cholesterol: LDL (low-dens...
Statement 1: LDL (low-density lipoprotein) carries cholesterol from other parts of your body back to your liver.
Explanation:
- LDL (low-density lipoprotein) is often referred to as "bad cholesterol" because it carries cholesterol from the liver to the cells in your body.
- It transports cholesterol to various tissues and organs, including the arteries.
- Cholesterol is an essential component of cell membranes and is required for the production of certain hormones and vitamin D.
- However, when there is an excessive amount of LDL cholesterol in the bloodstream, it can lead to the buildup of plaque in the arteries, increasing the risk of cardiovascular diseases.
Statement 2: A high level of LDL (low-density lipoprotein) cholesterol can lead to coronary artery disease.
Explanation:
- When LDL cholesterol levels are high, it can lead to the accumulation of cholesterol in the walls of the arteries, forming plaque.
- Over time, this plaque can narrow the arteries, reducing blood flow to the heart muscle.
- If the plaque ruptures, it can cause a blood clot to form, completely blocking the artery and leading to a heart attack.
- Coronary artery disease is a condition characterized by the narrowing and hardening of the coronary arteries, which supply oxygen-rich blood to the heart muscle.
- High levels of LDL cholesterol are one of the major risk factors for developing coronary artery disease.
Conclusion:
Both statements are correct. LDL cholesterol carries cholesterol from other parts of the body back to the liver, and a high level of LDL cholesterol can lead to coronary artery disease. Therefore, the correct answer is option B.

A novel vaccine aimed at reducing "bad" cholesterol has been created.
What is cholesterol?
- Cholesterol is a waxy, fat-like substance that's found in all the cells in your body.
- Your liver makes cholesterol, and it is also in some foods, such as meat and dairy products.
- Your body needs some cholesterol to work properly.
- What are LDL and HDL?
- Cholesterol travels through the blood on proteins called “lipoproteins.”
- Two types of lipoproteins carry cholesterol throughout the body: LDL (low-density lipoprotein) and HDL (high-density lipoprotein).
- LDL and HDL have different purposes.
- LDL cholesterol, sometimes called “bad” cholesterol, makes up most of your body’s cholesterol. A high LDL level leads to a buildup of cholesterol in your arteries.
- HDL cholesterol sometimes called “good” cholesterol, because it carries cholesterol from other parts of your body back to your liver. Your liver then removes the cholesterol from your body.
- How can a high LDL level raise my risk of disease?
- If you have a high LDL level, this means that you have too much LDL cholesterol in your blood.
- This extra LDL, along with other substances, forms plaque. The plaque builds up in your arteries; this is a condition called atherosclerosis.
- Coronary artery disease happens when plaque builds up is in the arteries of your heart. It causes the arteries to become hardened and narrowed, which slows down or blocks the blood flow to your heart. This can cause angina (chest pain) or, if the blood flow is completely blocked, a heart attack.
Hence only statement 2 is correct.
