Question

Which of the following statements about antibody molecules is not true?

Options

• All are proteins.

• All are immunoglobulins.

• All have light and heavy chains.

• All are produced by T-cells.

Answer 1

All are produced by T-cells.

Explanation:

All antibodies are proteins and are classified as immunoglobulins. All antibodies have light and heavy chains as structural components. However, antibodies are produced by plasma cells, which are differentiated B-cells, not by T-cells. T-cells assist in the immune response but do not produce antibodies themselves.
