Question

During endocytosis ___________________.

• A. The cell divides its cytoplasm during mitosis
• B. The cell digests itself
• C. The cell engulfs and internalizes materials using its
  membrane
• D. The cell enables the extracellular digestion of large
  molecules

Answer 1

The correct option is C The cell engulfs and internalizes materials using its

membrane
In endocytosis, the cell membrane also folds around a substrate to engulf and internalize it. In receptor-mediated endocytosis, this is a process that recognizes and targets a specific substrate through the help of integral membrane proteins on the cell membrane surface. Here integral membrane proteins called as receptor proteins recognize and bind to a specific target. When a receptor protein binds to a target, it signals the cell membrane to enclose the target and internalize it inside a specialized vesicle.
