Which type of cell transport is used by mitochondria to generate energy by allowing hydrogen (H ) ions to flow through a membrane protein?
Mitochondria utilize facilitated diffusion to generate energy by allowing hydrogen ions (H⁺) to flow through a membrane protein known as ATP synthase. This process occurs during oxidative phosphorylation, where the flow of H⁺ ions down their concentration gradient drives the synthesis of ATP from ADP and inorganic phosphate. The movement of these ions is aided by the electrochemical gradient established by the electron transport chain.
Hydrogen ion movement and atp formation?
During cellular respiration, hydrogen ions are moved across the inner mitochondrial membrane through the electron transport chain. This movement creates an electrochemical gradient that drives ATP synthesis through ATP synthase. The flow of hydrogen ions back through ATP synthase powers the phosphorylation of ADP to ATP.
What forces hydrogen ions to flow through the F0 subunit?
The proton gradient across the membrane is the driving force that compels hydrogen ions to flow through the F0 subunit of the ATP synthase complex. This gradient creates a proton motive force that powers the rotation of the rotor in the F0 subunit, converting the proton flow energy into mechanical energy to produce ATP.
What is the role of hydrogen ions in the conversion of ADP to ATP?
it is caused by the hydrogen ion flow across the membrane.
What ions accumulate in the outer compartment of the mitochondria during electron transport phosphorylation?
Protons (H+) accumulate in the outer compartment of the mitochondria during electron transport phosphorylation. This forms an electrochemical gradient that drives ATP synthesis as protons flow back into the mitochondrial matrix through ATP synthase.
A protein channel in a hydrogen ion pump is shown below?
Protein channels in hydrogen ion pumps, such as the F0 portion of ATP synthase, facilitate the movement of hydrogen ions (protons) across a membrane. This movement creates an electrochemical gradient that is used to generate ATP in cellular respiration. The protein channel allows only hydrogen ions to pass through, maintaining the integrity of the membrane.

Which protein complex allows hydrogen ions to rush out of the thylacoid providing energy that can be used to make a molecule?
ATP synthase is the protein complex that allows hydrogen ions to flow out of the thylakoid membrane during photosynthesis. This flow of hydrogen ions creates a proton gradient that drives the production of ATP, which is a molecule that stores energy for the cell to use.
What is the name and function of the protein channel where hydrogen ions escape into the matrix of the mitochondrion?
The protein channel is called ATP synthase. It functions in the mitochondrion by allowing hydrogen ions to flow back into the matrix through the channel, which generates ATP in the process known as oxidative phosphorylation.
What molecule will form when hydrogen ions flow down the electrochemical gradient through ATP synthesis complexes in mitochondria?
The molecule formed when hydrogen ions flow down the electrochemical gradient through ATP synthesis complexes in mitochondria is adenosine triphosphate (ATP). This process is known as oxidative phosphorylation, and it involves the production of ATP from the energy released by the flow of hydrogen ions through ATP synthase.
Hydrogen ion movement and atp formation?
During cellular respiration, hydrogen ions are moved across the inner mitochondrial membrane through the electron transport chain. This movement creates an electrochemical gradient that drives ATP synthesis through ATP synthase. The flow of hydrogen ions back through ATP synthase powers the phosphorylation of ADP to ATP.
The carrier protein that transports hydrogen ions across thylakoid membranes and produce ATP acts as both?
The carrier protein that transports hydrogen ions across thylakoid membranes and produces ATP acts as both a pump and an enzyme. It uses the energy from the movement of hydrogen ions to generate ATP through chemiosmosis.
Hydrogen ions flow back into the inner compartment through?
ATP synthase, a protein complex embedded in the inner mitochondrial membrane. This process is known as chemiosmosis and drives the synthesis of ATP from ADP and inorganic phosphate.
How do the hydrogen ions diffuse back?
Hydrogen ions diffuse back through the ATP synthase protein complex located on the inner mitochondrial membrane. This process harnesses the energy from the electrochemical gradient to produce ATP.
What forces hydrogen ions to flow through the F0 subunit?
The proton gradient across the membrane is the driving force that compels hydrogen ions to flow through the F0 subunit of the ATP synthase complex. This gradient creates a proton motive force that powers the rotation of the rotor in the F0 subunit, converting the proton flow energy into mechanical energy to produce ATP.
Is the movement of ions through a protein pump an active or passive process?
The movement of ions through a protein pump is an active process.
Why is hydrogen peroxide a good conductor for electricity?
Hydrogen peroxide is a good conductor of electricity because it contains ions that can move freely, allowing electric current to flow through it. The presence of these ions in the solution makes hydrogen peroxide able to conduct electricity.
