Mark each statement as either true or false. Rewrite false statements to make them true by changing the underlined words.

__________ Cytotoxic T cells secrete immunoglobulin.

Verified step by step guidance

1. Identify the role of cytotoxic T cells in the immune system.
2. Understand what immunoglobulins are and which cells secrete them.
3. Determine if cytotoxic T cells are responsible for secreting immunoglobulins.
4. If the statement is false, identify the correct cell type that secretes immunoglobulins.
5. Rewrite the statement by replacing the incorrect term with the correct one.

Key Concepts

Cytotoxic T Cells

Cytotoxic T cells, also known as CD8+ T cells, are a type of immune cell that directly kill infected or cancerous cells. They recognize antigens presented by Major Histocompatibility Complex (MHC) class I molecules on the surface of these target cells. Unlike B cells, which produce antibodies, cytotoxic T cells use perforin and granzymes to induce apoptosis in their targets.

Immunoglobulin

Immunoglobulins, or antibodies, are glycoproteins produced by B cells that play a crucial role in the immune response. They bind to specific antigens, marking them for destruction by other immune cells. There are five main classes of immunoglobulins (IgA, IgD, IgE, IgG, and IgM), each with distinct functions in immune defense.

Adaptive Immunity

Adaptive immunity is a specific immune response that develops over time and involves the activation of lymphocytes, including B cells and T cells. This system provides long-lasting protection against pathogens through memory cells that remember past infections. It is characterized by its ability to recognize specific antigens and mount a tailored response, distinguishing it from the innate immune system.
