Answer :
In this scenario, the information provided outlines the process of LDL (low-density lipoprotein) and its interaction with receptors on liver cell membranes. Here is a step-by-step breakdown of the situation:
1. Normal LDL binds to receptors on the liver cell membrane. This binding allows LDL to be taken into the cell.
2. However, in the case of defective LDL, it cannot bind to LDL receptors effectively. This means that the defective LDL is unable to be taken into the liver cell.
3. As a result of the defective LDL not being taken in by the liver cell, the liver compensates by producing more cholesterol.
4. With the liver producing more cholesterol due to the defective LDL, cholesterol levels in the body become elevated or high.
In summary, the inability of defective LDL to bind to LDL receptors on liver cells leads to increased cholesterol production by the liver, resulting in high cholesterol levels in the body. This situation highlights the importance of proper LDL function in maintaining cholesterol balance within the body.
