The real energy values (adjusted for the body's inefficiency) of foods that are digested and absorbed are called

Physiological fuel values are real energy values of foods that are digested and absorbed in which it can be determined using a bomb calorimeter to measure the heat of combustion of a particular food. A bomb calorimeter uses adiabatic conditions to monitor the heat temperature change inside the device.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
