Why are 4 H+ needed for every ATP synthesized and exported by mitochondria, even though only 3 H+ need to be translocated by the
kykrilka [37]

Answer: One H⁺ ion ie required in converting ATP and inorganic phosphate to ATP

Explanation:During oxidative phosphorylation, high energy electrons released by hydrogen carriers are shuttled through the electron transport chain. The released energy is used to translocate 3 H+ ions from the matrix, creating an proton motive force, which will cause 1 H+ ion to move down the electrochemical gradient and diffuse back into the matrix (chemiosmosis) which is facilitated by ATP synthase. As the H+ moves through the ATP synthase this triggers the molecular rotation of the enzyme, synthesizing ATP

bixtya [17]
The body's immune system thinks what he/she is eating or inhaling is a pathogen.  The immune system sends white blood cells to attack.  This triggers an allergic reaction.
For example: I am allergic to asparagus (I'm not joking, I really am) and walnuts.  Anytime I eat one of those, my body's immune system thinks it's a pathogen for some reason and attacks and triggers an allergic reaction in me.  This makes my breathing hard and makes it really itchy.  Good thing it's not that severe so I can eat some if I want, but sometimes allergic reactions could cause hospitalization or death.
