Question

multiple choice question
what is agglutination?

the binding of oxygen to hemoglobin
the production of large antigen-antibody complexes
the production of blood, especially its formed elements
the binding of carbon monoxide to hemoglobin to form carboxyhemoglobin

Explanation:

To determine the correct answer, we analyze each option:

• "The binding of oxygen to hemoglobin" describes oxygenation of hemoglobin, not agglutination.
• "The production of large antigen - antibody complexes" is the definition of agglutination, as agglutination involves antibodies cross - linking antigens to form such complexes.
• "The production of blood, especially its formed elements" refers to hematopoiesis, not agglutination.
• "The binding of carbon monoxide to hemoglobin to form carboxyhemoglobin" is carbon monoxide poisoning - related binding, not agglutination.

Answer:

B. The production of large antigen - antibody complexes
