How do electron transport reactions generate the proton motive force quizlet?

How do electron transport reactions generate the proton motive force quizlet?

How do electron transport reactions generate the proton motive force? The resulting separation of H+ and OH- charges along the membrane causes a difference in charge, pH, and electrochemical potential that energizes the membrane like a battery.

How is the proton motive force generated during electron transport How do cells generate ATP from a proton motive force?

The proton motive force occurs when the cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it. ATP synthesis is linked to the proton motive force through oxidative phosphorylation, where a phosphate group is added to ADP.

What is the proton motive force and how is it generated?

proton-motive force. energy that is generated by the transfer of protons or electrons across an energy-transducing membrane and that can be used for chemical, osmotic, or mechanical work.

How is the proton motive force obtained in cells and how does it drive the production of ATP in cellular respiration?

The proton-motive force created by the pumping out of protons by the respiratory chain complexes is in the mitochondria of most tissues mainly used to translocate protons through the ATP synthase complex, leading to the formation of ATP from adenosine diphosphate (ADP) and phosphate.

Which of the following generates the proton motive force PMF?

Answer: The proton-motive force is generated by the c. pumping of hydrogen ions from the mitochondrial matrix across the inner membrane and into the intermembrane space.

What does the proton motive force power?

Proton motive force (PMF) is the force that promotes movement of protons across membranes downhill the electrochemical potential.

What is the proton motive force and how is it generated How does the proton motive force result in ATP biosynthesis?

Which of the following processes generates a proton motive force in mitochondria?

Where is the proton motive force coming from in photosynthesis?

Introduction. Plant photosynthesis generates reducing power in the chloroplast stroma. During this process protons are transferred from the stroma into the thylakoid lumen, which generates a proton motive force (pmf) across the thylakoid membrane [1, 2].

Is proton motive force active transport?

Collapse of a proton gradient provides a proton-motive force which can drive the active transport of sugars. Since the energy to make the initial ion gradients usually comes from ATP hydrolysis, ATP indirectly powers the transport of the other species against a gradient.

What is proton motive force *?
