10 Questions
Which lipoprotein transports cholesterol from liver to peripheral tissues?
LDL
Which lipoprotein is known as 'the bad cholesterol'?
LDL
Which lipoprotein transports cholesterol from peripheral tissues to the liver?
HDL
Which lipoprotein is closely associated with increased risk for heart disease based on the number of particles?
LDL
Which lipoprotein is produced by the liver and intestine?
HDL
What is the function of LDL in cholesterol transport?
LDL transports cholesterol from the liver to peripheral tissues as part of the cholesterol transport pathway.
How does HDL protect against atherosclerosis?
Elevated HDL levels protect against atherosclerosis by removing cholesterol from vessel walls and transporting it to the liver where it is removed from the body.
What is the significance of the number of LDL particles in relation to heart disease risk?
It has been shown that the higher the number of LDL particles, the higher is the risk for heart disease.
Why are decreased HDL levels considered atherogenic?
Decreased HDL levels are considered atherogenic because HDL is involved in the reverse cholesterol transport pathway, and lower levels can lead to inadequate cholesterol removal from vessel walls.
What are lipoproteins and how are they formed?
Lipoproteins are formed by combining specific proteins with insoluble lipids in order to transport them in plasma.
Test your knowledge of cholesterol, lipoproteins, and their role in transporting lipids in the body with this informative quiz. Learn about LDL (low density lipoprotein) and its impact on heart disease risk.
