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 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 term describes the difference between the numbers of hydrogen ions on opposite sides of the membrane?
Diffusion and it does not have to be through a semi permeable membrane.
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.
Hydrogen ions move from the outer to the inner compartment of the mitochondria through what molecule?
Hydrogen ions move from the outer to the inner compartment of the mitochondria through the enzyme ATP synthase, which is embedded in the inner membrane. This movement of hydrogen ions creates an electrochemical gradient that drives ATP production.
When hydrogen ions are pumped from the mitochondrial matrix across the inner membrane and into the intermembrane space the result is?
Hydrogen ions are pumped through the membrane in the final stage of ATP generation in the electron transport chain. The ions pumped through the membrane create a gradient and cause the hydrogen to "want" to pass back through the membrane. They do so through the protein channels in the membrane and attaches a phosphate to adenosine diphosphate to make adenosine triphosphate.
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.
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.
The flow of what particle across the thylakoid membrane powers the production of ATP?
Protons (H+) flow across the thylakoid membrane during photosynthesis, creating a proton gradient. This gradient is used by ATP synthase to generate ATP from ADP and inorganic phosphate.
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.
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.
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.
Why sodium and hydrogen ions do not diffuse at the same rate?
Sodium and hydrogen ions have different molecular sizes and charges, affecting their diffusion rates through cell membranes. Sodium ions are larger and carry a positive charge, while hydrogen ions are smaller and uncharged. This leads to differences in how they interact with the membrane proteins and pores, influencing their ability to diffuse across the membrane.
What is chemiosmotic generation of ATP driven by?
Chemiosmotic generation of ATP is driven by the proton gradient across a membrane. This gradient is established by pumping protons across the membrane, creating a difference in proton concentration and charge that drives the movement of protons back across the membrane through ATP synthase, resulting in the synthesis of ATP.
What term describes the difference between the numbers of hydrogen ions on opposite sides of the membrane?
Diffusion and it does not have to be through a semi permeable membrane.
Diffusion across the cell membrane results in depolarization?
Through a systematic flow of potassium,calcium and sodium ions. Ie. slower acting gates alow timed flow of these ions while a contraction of these cells pushes out ions to restart the resting membrane potiential.
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.
