What is the product made by the electron transport chain the options are glucose adp pyruvate atp

we know automatically that glucose and pyruvate are wrong answers due to the fact that glucose is sugar and that pyruvate is a type of acid. this just leaves us with ADP and ATP now ADP and ATP are very close answers, since ADP is what makes ATP, but an electron transport change usually involves the transfer of electrons well if we look at their chemical formulas, we can see that ATP has more 1 more oxygen than ADP, and this kind of chain usually adds additional oxygen which gives us ATP as our answer.

electron transport chain in biology involves transfer of electrons n protons across a membrane. a electrical gradient is created from such transfer. it is how energy is stored thro' creation of ATP which stands for  adenosine triphosphate.

answer: - b cells

explanation: -

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.
