Final answer:
LDL (low-density lipoprotein) is taken into the cell through a process called receptor-mediated endocytosis. Specific binding proteins in the plasma membrane recognize and bind to the LDL particles, causing the plasma membrane to invaginate and bring the LDL particles into the cell.
Step-by-step explanation:
LDL (low-density lipoprotein) is taken into the cell through a process called receptor-mediated endocytosis, which is a targeted variation of endocytosis. In this mechanism, specific binding proteins in the plasma membrane recognize and bind to the LDL particles, causing the plasma membrane to invaginate and bring the LDL particles into the cell.
This process ensures that LDL, also known as 'bad' cholesterol, is removed from the blood. This process ensures that LDL, also known as 'bad' cholesterol, is removed from the blood.
