Final answer:
Cytotoxic T cells can mount an immune response more quickly than natural killer cells.
Step-by-step explanation:
Cytotoxic T cells can mount an immune response more quickly than natural killer cells. This statement is true.
Cytotoxic T cells, also known as CD8+ T cells, are a type of immune cell that directly kill infected cells. They are a part of the adaptive immune system and play a crucial role in protecting against viral infections. Once activated, cytotoxic T cells rapidly proliferate and identify infected host cells, leading to a quick immune response.
On the other hand, natural killer cells, although they are also involved in the immune response, are part of the innate immune system. They provide immediate defense against viruses and tumors by identifying and killing abnormal cells that have lost normal cell surface markers. However, the response of natural killer cells may not be as rapid as that of cytotoxic T cells.
