What is the formation of ATP by movement of H plus across a membrane through ATP synthase?
ATP formation occurs through a process called oxidative phosphorylation, where protons (H⁺ ions) move across a membrane via ATP synthase, an enzyme located in the inner mitochondrial membrane. This movement creates a proton gradient, with a higher concentration of H⁺ ions outside the mitochondrial matrix. As protons flow back into the matrix through ATP synthase, the energy released drives the phosphorylation of ADP to form ATP. This mechanism is a crucial part of cellular respiration, linking the electron transport chain to ATP production.

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 is the direct source of Energy ATP synthesis used to synthesize ATP?
Energy released from movement of protons through ATP synthase energy released from movement of protons through ATP synthase is the most direct source of energy in this case.
Where is ATP made in the mitochondria?
ATP is made in the mitochondria through a process called oxidative phosphorylation, which occurs in the inner membrane of the mitochondria. The electron transport chain generates a proton gradient across the inner membrane, which drives the production of ATP by ATP synthase.
Why is it important that a membrane separate the cellular regions on either side of an ATP synthase molecule in order for the protein to perform its function?
A membrane separation is crucial for ATP synthase to establish a proton gradient across the membrane. This gradient serves as the driving force for ATP synthesis as protons flow through the ATP synthase from high to low concentration. Without this separation, the necessary proton gradient cannot be generated.
At synthase in the chloroplast membrane makes atp utilizing the energy of highly concentrated?
ATP synthase in the chloroplast membrane synthesizes ATP by harnessing the energy from a proton gradient created during the light-dependent reactions of photosynthesis. As protons flow back into the stroma through the ATP synthase enzyme, this movement drives the conversion of ADP and inorganic phosphate (Pi) into ATP. The process is a crucial part of the overall energy transformation in photosynthesis, enabling the plant to store energy in a usable form.
H ions move through channels of what in the inner membrane?
H plus ions move through channels of the ATP synthase in the inner membrane. It is a type of enzyme that allows protons to move through the mitochondrial membrane.
What is the hydrogen ion movement and ATP formation?
During hydrogen ion movement, protons are transported across the inner mitochondrial membrane by the electron transport chain, creating an electrochemical gradient. This gradient is then used by ATP synthase to generate ATP from ADP and inorganic phosphate through a process called oxidative phosphorylation. ATP formation is coupled to proton movement, with the flow of protons driving the rotation of the ATP synthase complex to produce ATP.

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.
Can ATP synthase move about in the cytosol of the mitochondrian?
Definitely not, as ATP synthase is a membrane-bound enzyme. It is integrated into the inner mitochondrial membrane (and the thylakoid membrane in chloroplasts).
How many H ions are transported through the membrane during the formation of one ATP molecule?
One hydrogen ion is needed to pass through the ATP synthase in order for one ATP molecule to be created.
Where are the catalytic knobs of ATP synthase located?
The catalytic knobs of ATP synthase would be located on the stromal side of the membrane. Protons travel through ATP synthase from the thylakoid space to the stroma.
What is the direct source of Energy ATP synthesis used to synthesize ATP?
Energy released from movement of protons through ATP synthase energy released from movement of protons through ATP synthase is the most direct source of energy in this case.
Where are ATP synthase complexes located?
They are found in mitochondria and in chloroplasts.In mitochondria, the ATP synthase complexes are embedded in the inner membrane. In chloroplasts, the ATP synthase complexes are embedded in the thylakoid membranes.
Why aren't protons able to diffuse through the inner mitochondrial membrane?
Protons are unable to diffuse through the inner mitochondrial membrane because the membrane contains proteins called ATP synthase that provide a specific pathway for protons to pass through. This selective permeability allows protons to be utilized by ATP synthase to generate ATP during oxidative phosphorylation.

ATP is made in the mitochondria through a process called oxidative phosphorylation, which occurs in the inner membrane of the mitochondria. The electron transport chain generates a proton gradient across the inner membrane, which drives the production of ATP by ATP synthase.
