During respiration, as the electron transport chain is building an electrochemical gradient across the inner mitochondrial membrane, what happens to the pH of the intermembrane space?

Answer

pH becomes more basic.

No change in pH

The pH increases by 10-fold.

pH returns to neutral.

pH decreases

This one I have no idea, it doens't change at all?

pH is dependent on the concentration of H+ ions in a solution, more H+ more acidic, less H+ less acidic. As H+ decreases -OH will increase. So, to answer you need to know what is the atom used to build this gradient.

anonymous · Answer

H+? So because it is H+ means that more acidic?

@Tutormenoq2 Yep, which means that the pH does what?

anonymous · Answer

@mrdoldum Because there is an increase in H+ means that it will become more acidic? right.

anonymous · Answer

Which means the ph would decrease?

anonymous · Answer

lol sorry bout that.

anonymous · Answer

@Tutormenoq2 Yes, the pH decreases.
