b
it is NOT c. as the person below has chosen. Active transport requires energy to move substances against their concentration gradient. Thus it is directly coupled with the hydrolysis of ATP, thus dephosphorylating it. The person below is talking about the Electron Transport Chain which generates ATP and lots of it. In the electron transport, H+ accumulates outside the mitochondrial membrane and is transported PASSIVELY back into the membrane down its concentration gradient to drive the activity of ATP synthase to produce ATP via oxidative phosphorylation.
i think it may be passive because of the fact which you didnt use any tension to make the vinegar go into the egg. I additionally don't think that there have been any pumps interior the cellular membrane to make it lively transport. It subtle around the egg shell, making it passive transport
