The CTL has specific receptors that can recognize infected or damaged cells.
Explanation:
The cytotoxic T cells (CTL) is a type of white blood cells that specifically helps in destroying virus-infected cells (also damaged cells and cancer cells).
This type of cells has a special receptor called T-cells receptors (TCR) which ones recognize specific antigens (molecule that stimulate the immune systems because are “strange” to them). Virus inside a cell could bind to a special molecule called class I MHC, this molecule moves the virus to the surface of the cell where it can be recognized by a CD8+ specific antigen-receptor of the CTL.
The one that is true about cells is Number two. The cell is the basic unit of a structure and function of life. The cells are what makes us living things. All living things are made up of cells.
