where does the energy come from to form...? where does the energy come from to form ATP from ADP and PWeegy:
It does depend; your question is vague. I will address the combining of ADp and Pi to form ATP in mitochondria via oxidative phosphorylation.
The electron transport system uses the energy released as electrons fall to lower energy levels (as they are passed between molecules in the mitochondrial inner membrane) to pump protons unidirectionally across the mitochondrial inner membrane, up their concentration gradient, into the intermembrane space. Since the protons cannot diffuse back through the membrane, a electrochemical gradient across the inner mitochondrial membrane is formed. This is a form of potential energy (analogous to a dam holding back a lake of water).
The potential energy of the proton gradient is converted into kinetic energy as the protons flow back into the matrix, through membrane-spanning enzymes called ATP synthases. The flow of protons through the ATP synthase causes a central shaft to rotate. This leads to a cyclic change between 3 conformations in a binding site, each of which has a different affinity for ADP and ATP. So ADP and Pi bond, then are squeezed together to form ATP, and then ATP is released, and the next cycel begins.Auto Answered|Score 1Weegy:
