Final answer:

Cytotoxic T cells recognize antigens presented on MHC class I molecules and kill target cells expressing those antigens.

Step-by-step explanation:

The cells that recognize antigens presented on MHC class I molecules and act to kill target cells expressing those antigens are Cytotoxic T cells. Cytotoxic T cells are part of the adaptive immune response and play a crucial role in eliminating infected or abnormal cells.

When a virus or other intracellular pathogen infects a cell, it presents small pieces of the pathogen on its MHC class I molecules. Cytotoxic T cells recognize these antigens and release toxic substances to kill the infected cell.
