chemiosmosis

The light reactions of photosynthesis generate energy by chemiosmosis.

He linked this process to osmosis, the diffusion of water across a membrane, which is why it is called chemiosmosis.

Bacteria and archaea also can use chemiosmosis to generate ATP.

These electrons move through structures in chloroplasts and by chemiosmosis, make ATP.

In fact, mitochondria and chloroplasts are believed to have been formed when early eukaryotic cells ingested bacteria that could transfer energy using chemiosmosis.

The protons return to the mitochondrial matrix through the process of chemiosmosis through the protein ATP synthase.

ATP synthase is the enzyme that makes ATP by chemiosmosis.

This process is called chemiosmosis, and was first described by Peter Mitchell who was awarded the 1978 Nobel Prize in Chemistry for his work.

The energy released generates adenosine triphosphate (ATP) through chemiosmosis, in the same basic process that happens in the mitochondrion of eukaryotic cells.

The generation of ATP by chemiosmosis occurs in chloroplasts and mitochondria as well as in most bacteria and archaea.

The components of the biological thermosynthesis machinery concern progenitors of today's ATP synthase, which functions according to the binding change mechanism, driven by chemiosmosis.

Some of the CO is reacted with the hydrogen to produce methane, which creates an electrochemical gradient across cell membrane, used to generate ATP through chemiosmosis.

In addition, membranes in prokaryotes and in the mitochondria and chloroplasts of eukaryotes facilitate the synthesis of ATP through chemiosmosis.

This energy fall is harnessed, (the whole process termed chemiosmosis), to transport hydrogen (H) through the membrane, to the lumen, to provide a proton-motive force to generate ATP.

This transport chain produces a proton-motive force, pumping H ions across the membrane; this produces a concentration gradient that can be used to power ATP synthase during chemiosmosis.

This store of energy is tapped by allowing protons to flow back across the membrane and down this gradient, through a large enzyme called ATP synthase; this process is known as chemiosmosis.

As a result, chemiosmosis occurs, producing ATP from ADP and a phosphate group when ATP synthase harnesses the potential energy from the concentration gradient formed by the amount of H ions.

Lactic acid bacteria convert malic into lactic as an indirect means of creating energy for the bacteria by chemiosmosis which utilizes the difference in pH gradient between inside the cell and outside in the wine to produce ATP.

The electrochemical potential difference between the two sides of the membrane in mitochondria, chloroplasts, bacteria, and other membranous compartments that engage in active transport involving proton pumps, is at times called a chemiosmotic potential or proton motive force (see chemiosmosis).

Both the electron transport chain and the ATP synthase are embedded in a membrane, and energy is transferred from electron transport chain to the ATP synthase by movements of protons across this membrane, in a process called chemiosmosis.

As a concentration gradient of hydrogen ions forms, a protein called ATP synthase harnesses the potential energy of these ions and starts chemiosmosis, where the H+ ions reenter the matrix via this enzyme bound to the cristae (folds of the inner membrane).

A steep H+ gradient is formed, which allows chemiosmosis to occur, where the thylakoid, transmenbrane ATP-synthase serves a dual function as a "gate" or channel for H+ ions and a catalytic site for the formation of ATP from ADP + a P0-4 ion.
