There are choices for this question namely:
<span>A) B cells produce IgE antibodies
B) B cells release cytokines
C) cytotoxic T cells present the class II MHC molecule-antigen complex on their surface
D) helper T cells release cytokines
The correct answer is "helper T cells release cytokines". Cytokines are released by helper T cells when B cells attach to them via receptors. These T cells "help" these B cells to differentiate by secreting certain cytokines. When B cells differentiate, they are converted to plasma cells and able to secrete antibodies to the antigen presented to the T cells. </span>
A mutation in human ATPase 6 from leucine to
arginine at position 156 may allow the movements of protons across the
membrane, but not rotating of the ring of c subunits.
This possible mechanism affect the function of
ATP synthase because there would be an uncoupling of proton translocation and ATP
synthesis. ATP synthase would remain sensitive to F0 proton conduction
inhibitors
