What is the function of the enzyme ATP synthase?
The function of ATP synthase is to synthesize ATP from ADP and inorganic phosphate (Pi) in the F1 sector. This is possible due to energy derived from a gradient of protons which cross the inner mitochondrial membrane from the intermembrane space into the matrix through the Fo portion of the enzyme.
Does chemiosmosis require ATP synthase?
Chemiosmosis is the mechanism used by oxidative phosphorylation to directly make ATP. However, ATP synthase will not be able to do so without the proton motive force that results from the ETC that moves protons (H+) to the other side of the membrane as the electrons are passed along the chain.
How does the ATP synthase protein membrane work in cellular respiration?
ATP synthase is an enzyme that directly generates adenosine triphosphate (ATP) during the process of cellular respiration. ATP synthase forms ATP from adenosine diphosphate (ADP) and an inorganic phosphate (Pi) through oxidative phosphorylation, which is a process in which enzymes oxidize nutrients to form ATP.
What is the purpose of chemiosmosis quizlet?
Chemiosmosis involves the establishment of a proton gradient across a membrane- used to drive ATP Synthesis. Energy from the electrons is used to transport H+.
What is the role of chemiosmosis in photosynthesis?
The ions flow through ATP synthase from the thylakoid space into the stroma in a process called chemiosmosis to form molecules of ATP, which are used for the formation of sugar molecules in the second stage of photosynthesis.
What happens during chemiosmosis in photosynthesis?
What is chemiosmosis in cellular respiration?
Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient. An important example is the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H+) across a membrane during cellular respiration or photosynthesis.

How does ATPase break down ATP?
Although ATP hydrolysis is a favorable reaction, ATP does not breakdown on its own. ATPases help overcome this repulsion by surrounding the ATP molecule with positive ions that interact with the negative charged ions on the phosphate molecule, allowing hydrolysis to take place.
