ATP molecules are essentially cellular energy currency. The hydrogen gradient (or proton gradient as it is technically called) is responsible for the functioning of a protein complex called ATP synthase which in turn is responsible for the synthesis of ATP molecules. Therefore, the proton gradient is the driving force for the synthesis of ATP molecules.
The hydrogen ion gradient is maintained by the electron transport chain during cellular respiration. This process uses the energy from electrons to pump hydrogen ions across the inner mitochondrial membrane, establishing a gradient that drives the production of ATP through ATP synthase.
electron transport chain
The hydrogen ion gradient is used to drive ATP synthesis. 32 to 34 molecules of ATP are produced. The hydrogen ion gradient is the result of NADH in the electron transport system of the mitochondria.
Hydrogen pumps move hydrogen ions into the thylakoid lumen of chloroplasts during the process of photosynthesis. This creates a proton gradient across the thylakoid membrane, which is essential for ATP synthesis. In cellular respiration, similar proton pumps are found in the inner mitochondrial membrane, contributing to the generation of ATP through oxidative phosphorylation.
The hydrogen falls down its electrochemical gradient, from an area of high concentration to an area of lower concentration, through the ATP synthase and provides the force to power this synthase and synthesize ATP.

The enzyme that acts as a motor and generates the energy currency of the cell is ATP synthase. It is responsible for synthesizing adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate (Pi) using the energy generated by the hydrogen ion gradient across the inner mitochondrial membrane during cellular respiration.

Protons (H+) are the main molecules responsible for creating a chemiosmotic gradient across biological membranes. In cellular respiration, the electron transport chain pumps protons across the inner mitochondrial membrane, creating a gradient that drives ATP synthesis through ATP synthase.

The movement of hydrogen ions across a mitochondrial membrane.
Hydrogen ions are pumped through the membrane in the final stage of ATP generation in the electron transport chain. The ions pumped through the membrane create a gradient and cause the hydrogen to "want" to pass back through the membrane. They do so through the protein channels in the membrane and attaches a phosphate to adenosine diphosphate to make adenosine triphosphate.
Chemiosis, also known as chemiosmosis, is a process that occurs during cellular respiration and photosynthesis. It involves the movement of ions across a membrane to generate ATP, the energy currency of the cell. Chemiosis relies on an electrochemical gradient to drive the production of ATP.
ATP synthase is the enzyme that generates ATP using the concentration gradient of hydrogen ions. It is located in the inner mitochondrial membrane and uses the energy from the flow of hydrogen ions down their concentration gradient to convert ADP and inorganic phosphate into ATP.
