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.
What happens as ATP is synthesized in the electron transport chain?
During ATP synthesis in the electron transport chain, energy is used to pump protons across the inner mitochondrial membrane, creating a proton gradient. This gradient drives the flow of protons back across the membrane through ATP synthase, which couples the movement of protons to the synthesis of ATP from ADP and inorganic phosphate. This process is known as oxidative phosphorylation.
What is the role of atp sythase in photosynthesis?
The hydrogen ions pumped across the innermembrane into the thylacoid space fall down the electrochemical gradient through the ATP synthase where ADP is phosphorylated into ATP which is then used in the Calvin cycle rearrangements of carbon fixed intermediates to produce the gyceraldehyde-3-phosphate sugar the plants need. Simplified explanation.
What supplies the process during the initial process of photosynthesis that drives ATP synthesis?
sunlight
ATP is formed when the thylakoid compartment?
ATP is formed when the thylakoid compartment of the chloroplast generates a proton gradient through the process of photosynthesis. This proton gradient is used by the ATP synthase enzyme to catalyze the formation 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.
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.
Where does the energy come from to make ATP at the chloroplast?
From the motion of hydrogen ions from the kinetic energy of hydrogen ions passing through ATP synthase
What drives ATP synthase reactions the produced ATP?
Inside the intermembrane space, there is a buildup of hydrogen ions from the ETC. The hydrogen ions go down the concentration gradient through ATP synthase, producing 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.

The hydrogen ions pumped across the innermembrane into the thylacoid space fall down the electrochemical gradient through the ATP synthase where ADP is phosphorylated into ATP which is then used in the Calvin cycle rearrangements of carbon fixed intermediates to produce the gyceraldehyde-3-phosphate sugar the plants need.
