In most cases the proton-motive force is generated by an electron transport chain which acts as a proton pump using the Gibbs free energy of redox reactions to pump protons hydrogen ions out across the membrane separating the charge across the membrane. Two components of proton-motive force 1.
Cellular Respiration Electron Transport Chain
It is a form of energy that arises due to differences in pH across biological membranes.

Trapping the ions on either side of the membrane creates two things which together make the proton motive force. All bacteria require a proton motive force pmf to grow and remain viable under replicating and non-replicating conditions. The Proton Motive Force By Jennifer Stearns Michael Surette The proton motive force occurs when the cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it.

The proton motive force occurs when the cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it. The proton motive force occurs when the cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it.
What is proton-motive force. A the force required to remove an electron from hydrogen B the force exerted on a proton by a transmembrane proton concentration gradient C the force that moves hydrogen into the intermembrane space D the force that moves hydrogen into the mitochondrion E the force that moves hydrogen to NAD. Energy storage in membrane.
The product of the electron transport chain. Stored as chemical and electrical chemical is pH difference on each side of membrane lower pH outside due to more H ions. What does the proton-motive force cause in terms of the active sites.
Learn vocabulary terms and more with flashcards games and other study tools. Basically this causes the cell to act like a tiny battery. A higher concentration of protons outside the inner membrane of the mitochondria than inside the membrane is the driving force behind ATP.
Proton motive force PMF is the force that promotes movement of protons across membranes downhill the electrochemical potential. Its energy can either be used right away to do work like power flagella or be stored for later in ATP. Proton gradient is generated by oxidation of NADH and FADH2 is called proton motive force and powers ATP synthesis.
