Question 1

According to the study of Steensberg et al. (2001b), how did acute prolonged strenuous exercise affect the proportion of circulating helper T cells?

Accepted Answer

C,D

Question 2

Which of the following is not a mitogen stimulant?

Accepted Answer

Tetanus toxoid is not a mitogen stimulant. It is a vaccine used to prevent tetanus infection. The others listed are all known mitogen stimulants.

Question 3

In the study by Green et al. (2002), PHA-stimulated lymphocyte proliferation in a fixed number of lymphocytes fell after a one-hour intensive treadmill run but what happened to the proliferative response when natural killer cells were removed from the proliferation cultures?

Accepted Answer

The removal of natural killer cells from the proliferation cultures resulted in a lower proliferative response compared to the cultures where NK cells were present.

Question 6

What is the predominant immunoglobulin in the blood?

Accepted Answer

IgG is the predominant immunoglobulin in the blood, comprising around 75% of total immunoglobulin in the plasma. It is involved in secondary immune responses and provides long-term protection against pathogens.

...

Question 9

In vivo assessments of both cell-mediated immune responses and antibody production suggest that the initial primary response is less affected by exercise than subsequent memory responses.

Question 10

Changes in T cell functions with acute exercise are related to the intensity but not the duration of the exercise bout.

Accepted Answer

Both the intensity and duration of exercise can influence T cell functions, as different exercise regimens can lead to varying immune responses.
