The chemiosmotic production of ATP through photophosphorylation in photosynthesis is closely related to the chemiosmotic production of ATP through oxidative phosphorylation in cellular respiration. Both processes utilize a proton gradient across a membrane to power the ATP synthase which phosphorylates ADP into ATP.
What else can I help you with?
What does Chemiosmosis involves .?
The movement of hydrogen ions across a mitochondrial membrane.
The movement of protons during ATP production is called what?
The movement of protons during ATP production is called chemiosmosis. In this process, protons are pumped across a membrane, creating an electrochemical gradient that drives ATP synthesis.
Once ATP is converted into ADP p it must be a disassembled into components sugar base phosphates and then reassembled b recharged by chemiosmosis c converted into nadph d processed?
b) recharged by chemiosmosis ADP is rephosphorylated back into ATP through a process known as chemiosmosis, which occurs during cellular respiration or photosynthesis. This process utilizes a proton gradient across a membrane to drive the synthesis of ATP by the ATP synthase enzyme.
Which parts of the mitochondria are directly involved in the synthesis of ATP during chemiosmosis?
The inner mitochondrial membrane and the enzyme complex ATP synthase are directly involved in the synthesis of ATP during chemiosmosis. Protons are pumped across the inner mitochondrial membrane, creating a proton gradient that drives the production of ATP by ATP synthase through oxidative phosphorylation.
What happens during chemiosmosis?
During chemiosmosis, protons are pumped across the inner mitochondrial membrane, creating a proton gradient. The protons then flow back through ATP synthase, driving the synthesis of ATP from ADP and inorganic phosphate. This process is a key step in oxidative phosphorylation, the process by which cells generate ATP using energy derived from the electron transport chain.

What is location of ETC and chemiosmosis in photosynthesis and cellular respiration?
In photosynthesis, ETC and chemiosmosis occur in the thylakoid membranes of chloroplasts. In cellular respiration, these processes take place in the inner mitochondrial membrane. These locations are where the electron transport chain (ETC) pumps protons across the membrane, creating a proton gradient that drives ATP production through chemiosmosis.
Does chemiosmosis expend energy?
No, chemiosmosis does not expend energy. Instead, it utilizes the energy stored in the form of a proton gradient to drive ATP synthesis in processes such as oxidative phosphorylation in mitochondria or photosynthesis in chloroplasts.
When does non cyclic electron flow?
Non-cyclic electron flow occurs in the photosystems of plant chloroplasts during photosynthesis when electrons are transferred through both photosystem I and II to generate ATP and NADPH. This process does not involve the formation of ATP synthase or the production of ATP through chemiosmosis.
Could a plant cell produce ATP through chemiosmosis if the thylakoid membrane was leaky with regards to protons?
No, a leaky thylakoid membrane would disrupt the formation of a proton gradient necessary for ATP production through chemiosmosis during the light-dependent reactions of photosynthesis. Protons need to be pumped across the membrane to create a gradient, and the leak would prevent this build-up.
What is the relationship between chemiosmosis and ATP formation?
chemiosmosis is one of the processes that produces ATP. this happens in the inner membrane of the mitochondria.

Why does chemiosmosis require a membrane?
Chemiosmosis involves the movement of ions across a membrane, which creates an electrochemical gradient that drives ATP synthesis. The membrane is necessary to separate the high and low concentration of ions, allowing for the generation of the proton gradient that powers ATP production.
Which parts of the mitochondria are directly involved in the synthesis of ATP during chemiosmosis?
The inner mitochondrial membrane and the enzyme complex ATP synthase are directly involved in the synthesis of ATP during chemiosmosis. Protons are pumped across the inner mitochondrial membrane, creating a proton gradient that drives the production of ATP by ATP synthase through oxidative phosphorylation.
The production of ATP in photosynthesis is called?
it requires energy to be lost from the downhill movement of the excited electron from photosystem 2 to photosystem 1. the energy lost is coupled to ATP formation

The protons then flow back through ATP synthase, driving the synthesis of ATP from ADP and inorganic phosphate.
