Final answer:
A decrease in cholesterol receptor activity in liver cell membranes leads to an increase in LDL cholesterol levels.
Explanation:
A decrease in the activity of cholesterol receptors in liver cell membranes affects the concentration of LDL cholesterol in the blood.When the activity of cholesterol receptors decreases, it results in fewer receptors available to remove LDL cholesterol from the bloodstream, leading to an increase in LDL cholesterol levels. LDL receptors are crucial for the uptake and clearance of LDL cholesterol by cells, so a decrease in their activity hinders this process, causing higher LDL levels.
