Multiple Choice QuestionWhich of these is a lymphocyte that produces antibodies?Multiple choice question.NK cellB cellT cellMacrophage

Break Down the Problem

1. Identify the types of cells listed in the options: NK cell, B cell, T cell, and Macrophage.
2. Recall the function of each cell type, particularly focusing on their role in the immune system and antibody production.

Relevant Concepts

1. NK (Natural Killer) Cell: These are a type of lymphocyte that plays a role in the innate immune system by killing tumor and virus-infected cells but do not produce antibodies.
2. B Cell: B lymphocytes are responsible for producing antibodies. They differentiate into plasma cells that secrete antibodies to neutralize pathogens.
3. T Cell: T lymphocytes involve in cell-mediated immunity but do not produce antibodies.
4. Macrophage: These are immune cells that engulf and digest cellular debris and pathogens; they do not produce antibodies.

Analysis and Detail

• From the descriptions, it is clear that among the options, B cells are specialized for producing antibodies that bind to specific antigens, thereby playing a crucial role in the humoral immune response.

Verify and Summarize

• The function of B cells in antibody production has been confirmed, while the other cell types do not have this capability.

Final Answer

The lymphocyte that produces antibodies is B cell.
