Proton Gradient: This is a difference in proton concentration across a membrane. It's like having more people on one side of a room than the other, creating pressure for them to spread out evenly.
Enzyme:Enzymes are biological catalysts that speed up chemical reactions in cells. They're like super-efficient factory workers who can assemble products much faster than normal.
Adenosine Triphosphate (ATP):This is the main energy currency of cells. It's like money for cells - they use it to pay for all their activities and processes.
