Worked practice questions

A protein binds tightly to a molecule carried by a pathogen. That binding protein is an:

  1. Antibody
  2. Antacid
  3. Antigen
  4. Antenna
Show answer and solution

Correct answer: A. Antibody

1. The pathogen molecule it recognises is the antigen. 2. The protein that latches onto it is made by the immune system. 3. That protein is an antibody. _Source: OpenStax Anatomy and Physiology 2e, Chapter 21, The Lymphatic and Immune System._

The cells that carry out adaptive immune responses, including B and T cells, are the:

  1. Ligaments
  2. Lymphocytes
  3. Lipocytes
  4. Leucoplasts
Show answer and solution

Correct answer: B. Lymphocytes

1. Adaptive responses are specific and remembered. 2. One family of white cells does that work. 3. They are the lymphocytes. _Source: OpenStax Anatomy and Physiology 2e, Chapter 21, The Lymphatic and Immune System._

Unlike a B cell, one lymphocyte type never secretes antibody but performs other adaptive roles. That is the:

  1. T cell
  2. Red cell
  3. Mast cell
  4. Stem cell
Show answer and solution

Correct answer: A. T cell

1. B cells become plasma cells and pour out antibody. 2. The other main lymphocyte works by direct action and signalling instead. 3. That is the T cell. _Source: OpenStax Anatomy and Physiology 2e, Chapter 21, The Lymphatic and Immune System._
