Question

Consumed by the cell by endocytosis, inside the cell, the cholesterol is broken down and used to make a variety of other useful molecules, such as the ________?

1) lipids
2) proteins
3) carbohydrates
4) nucleic acids

Answer 1

Inside the cell, cholesterol is broken down and used to make other useful molecules such as 1) lipids.

Step-by-step explanation:

Lipids serve in the breakdown of stored energy molecules, as signaling molecules, and as channels for protein transport. Dietary triacylglycerols are transported through the bloodstream in chylomicrons. When a chylomicron encounters the enzyme lipoprotein lipase, triacylglycerols are broken down by hydrolysis into fatty acids and glycerol.

These breakdown products then pass through capillary walls to be used for energy by cells or stored in adipose tissue as fat. Liver cells combine the remaining chylomicron remnants with proteins, forming lipoproteins that transport cholesterol in the blood.

Cholesterol is broken down inside the cell to make lipids. These lipids play roles in energy storage, signaling, and protein transport. Understanding the metabolism of cholesterol and lipids is crucial for understanding the functions and processes within cells. Therefore, the correct answer is 1) lipids. Cholesterol is broken down inside the cell and used to make various lipids that serve important functions in the body.
