Answer :
Final answer:
IgM antibodies function within the human body and do not have a specific temperature at which they 'react'. They function typically at the internal body temperature of a human, approximately 37 degrees Celsius. However, their functionalities aren't switched 'on or off' by specific temperatures.
Explanation:
The question asks 'At what temperature do IgM antibodies react?' It's important to note that the question as posed may have some misconceptions embedded within it. As far as the biology of IgM antibodies is concerned, they do not have a specific temperature at which they react. The function of the antibodies doesn't directly depend on temperature. They exist and function within the human body, typically operating at an internal body temperature around 37 degrees Celsius, but their functions, such as binding to antigens, do not 'turn on or off' at specific temperatures. Rather, the efficacy of the immune response as a whole can be impacted by factors such as fevers (higher body temperatures) but this isn't an on/off switch for these antibodies' functionalities.
