Chemiosmosis:
Chemiosmosis is the process by which ATP is produced in the inner membrane of a mitochondrion. It involves the transfer of protons (H+) from the inner compartment of the mitochondrion to the outer compartment. As the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP.
Electron Transport System:
The electron transport system is a series of proteins located in the inner mitochondrial membrane. It plays a crucial role in the production of ATP through chemiosmosis. During the electron transport system, electrons are transferred from electron donors (such as NADH and FADH2) to electron acceptors (such as oxygen) through a series of redox reactions. This transfer of electrons creates a proton gradient across the inner mitochondrial membrane.
Proton Transfer:
As electrons move through the electron transport system, protons are pumped from the inner compartment of the mitochondrion to the outer compartment. This creates a higher concentration of protons in the outer compartment compared to the inner compartment, establishing an electrochemical gradient.
Flow of Protons:
The electrochemical gradient created by the transfer of protons drives the flow of protons back into the inner compartment of the mitochondrion. This flow of protons is facilitated by ATP synthase, which acts as a molecular turbine. As protons flow through ATP synthase, the energy of their movement is harnessed to add phosphate to ADP, forming ATP.
Phosphorylation:
The addition of a phosphate group to ADP to form ATP is known as phosphorylation. In the context of chemiosmosis, this phosphorylation occurs as a result of the energy released by the flow of protons back into the inner compartment. ATP synthase, the enzyme responsible for this process, uses the energy from the proton flow to catalyze the phosphorylation reaction.
In conclusion, chemiosmosis is the process by which ATP is produced in the inner membrane of a mitochondrion. The transfer of protons during the electron transport system creates an electrochemical gradient, and as protons flow back into the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP.

Chemiosmosis: It is a process where diffusion of ions takes place across a selectively permeable membrane. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration. The enzyme ATP synthase helps synthesise ATP by chemiosmosis. Both photophosphorylation in chloroplasts and oxidative phosphorylation in mitochondria occurs according to the principles of chemiosmosis.
