What else can I help you with?
Why are protons (H) pumped across the inner mitochondrial membrane?
Protons (H) are pumped across the inner mitochondrial membrane to create a proton gradient, which is used to generate ATP through a process called oxidative phosphorylation. This ATP is the main source of energy for the cell.
Can ions diffuse through a membrane?
Yes, ions can diffuse through a membrane.
What moves across the inner mitochondrial membrane to synthesize ATP during chemiosmosis?
Protons (H+ ions) move across the inner mitochondrial membrane through ATP synthase to synthesize ATP during chemiosmosis. This process is driven by the proton gradient that is established during electron transport chain reactions.
Can pyruvate cross the mitochondrial membrane?
Yes, pyruvate can cross the mitochondrial membrane through specific transport proteins.
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).

Can ions diffuse through a membrane?
Yes, ions can diffuse through a membrane.
What is the effect of the flow of protons through the inner mitochondrial membrane?
The flow of protons through the inner mitochondrial membrane drives the synthesis of ATP through the process of oxidative phosphorylation. This flow creates a proton gradient, which is used by ATP synthase to produce ATP from ADP and inorganic phosphate. This process is known as chemiosmosis.
How does the cell use the charge differences that build up across the inner mitochondrial membrane during cellular respiration?
The charge differences across the inner mitochondrial membrane are used to generate ATP through a process called chemiosmosis. Protons are pumped across the membrane, creating a proton gradient. As protons flow back across the membrane through ATP synthase, ATP is produced. This process is essential for providing energy to the cell.
What possesses occurs across the mitochondrial membrane?
Mitochondrial membrane potential is generated by the electron transport chain (ETC) during oxidative phosphorylation, where electrons are transferred through a series of protein complexes. This process pumps protons (H⁺ ions) from the mitochondrial matrix into the intermembrane space, creating an electrochemical gradient. This gradient drives ATP synthesis as protons flow back into the matrix through ATP synthase. Additionally, various metabolites and ions can also cross the mitochondrial membrane via specific transporters, facilitating metabolic functions.
Which substances did not diffuse the membrane?
starch doesnt diffuse through the dialysis membrane.
What moves across the inner mitochondrial membrane to synthesize ATP during chemiosmosis?
Protons (H+ ions) move across the inner mitochondrial membrane through ATP synthase to synthesize ATP during chemiosmosis. This process is driven by the proton gradient that is established during electron transport chain reactions.
Can pyruvate cross the mitochondrial membrane?
Yes, pyruvate can cross the mitochondrial membrane through specific transport proteins.
What membrane is permeable to protons.?
The inner mitochondrial membrane is permeable to protons, specifically during the process of oxidative phosphorylation. This membrane contains protein complexes that facilitate the electron transport chain and the subsequent movement of protons (H⁺ ions) from the mitochondrial matrix to the intermembrane space, creating a proton gradient. This gradient is essential for ATP synthesis, as protons flow back into the matrix through ATP synthase, driving the conversion of ADP and inorganic phosphate into ATP.
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.
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).
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.
