Electron Transport SystemThe electron transport chain
The accumulation of protons occurs in the thylakoid space within the chloroplast during photosynthetic electron transport. This forms a proton gradient that drives ATP synthesis during the process of photophosphorylation.

ATP synthesis occurs in the inner mitochondrial membrane through a process known as oxidative phosphorylation. This process involves a series of protein complexes that use the energy generated by the flow of electrons along the electron transport chain to pump protons across the membrane, creating a proton gradient that drives the synthesis of ATP by ATP synthase.
The energy in ATP drives three main types of cellular work: mechanical work (such as muscle contraction), transport work (such as pumping ions across membranes), and chemical work (such as driving endergonic reactions).
Yes, dehydration synthesis releases energy. During this process, a water molecule is removed as two compounds bond together, resulting in the release of energy that drives the formation of the new bond.

The functioning of an electron transport chain is analogous to a relay race, where electrons are passed from one molecule to another in a stepwise fashion to generate energy. Just like how runners pass a baton to move forward, in the electron transport chain, electrons are passed along proteins in the inner mitochondrial membrane to create a proton gradient that drives ATP synthesis.
The synthesis of an ATP molecule from two ADP molecules involves the condensation reaction where a phosphate group is transferred from one ADP molecule to the other, forming a high-energy phosphoanhydride bond. This process is catalyzed by the enzyme ATP synthase, which is located in the inner mitochondrial membrane or thylakoid membrane in the cells. The energy for this reaction is usually derived from the electrochemical gradient across the membrane, which drives the rotation of ATP synthase and facilitates ATP synthesis.

There are multiple chemical pathways toward the synthesis of adenosine triphosphate (ATP) molecules. The second, and answer to this question is anaerobic respiration, such as the lactic acid cycle.
The accumulation of protons occurs in the thylakoid space within the chloroplast during photosynthetic electron transport. This forms a proton gradient that drives ATP synthesis during the process of photophosphorylation.

Like anything mechanical, hard drives will eventual wear out and need to be replaced.
When electrons move back to lower energy levels in an electron transport chain, energy is released. This energy is used to pump protons across a membrane, creating an electrochemical gradient that drives ATP synthesis.
