Chemisosmosis is generated by hydrogen ions passing through ATP synthases. The ATP synthase are the only patches of the membrane that are permeable to the hydrogen ions. The ATP synthase uses the flow of hydrogen ions to change ADP to ATP since enough energy is released by flow of hydrogen ions through the ATP synthase.
Chemiosmotic generation of ATP is driven by the proton gradient across a membrane. This gradient is established by pumping protons across the membrane, creating a difference in proton concentration and charge that drives the movement of protons back across the membrane through ATP synthase, resulting in the synthesis of ATP.
Chemiosmotic generation of ATP is driven by a gradient of H+ ions (protons). These protons move from high to low concentration, and in the process, power a protein that phosphorylates ADP into ATP.

Chemiosmosis in the thylakoid membrane is directly responsible for?
Chemiosmosis in the thylakoid membrane is directly responsible for the generation of ATP during photosynthesis. It involves the movement of protons across the thylakoid membrane to create a proton gradient, which drives the synthesis of ATP by ATP synthase enzyme.
What is the chemiosmosis production of ATP compared to in photosynthesis?
In cellular respiration, chemiosmosis occurs in the mitochondria and generates ATP through oxidative phosphorylation. In photosynthesis, chemiosmosis occurs in the thylakoid membrane of the chloroplast and generates ATP through photophosphorylation. Both processes involve creating a proton gradient that drives ATP synthesis, but the sources of energy (glucose oxidation vs. light absorption) and final electron acceptors (O2 vs. NADP+) differ between the two processes.
Is the glomerular filtration an ATP driven process?
No, glomerular filtration is not an ATP-driven process. It occurs passively based on the pressure gradient across the glomerular capillaries and the filtration barrier. ATP is mainly required for active processes in the kidney such as tubular reabsorption and secretion.
What contains enzymes used in the breakdown of glucose and generation of ATP?
Mitochondria
Another word for respiration?
Chemiosmotic phosphorylation
Synthesis of ATP by the chemiosmotic mechanism occurs during?
The synthesis of ATP by the chemiosmotic mechanism occurs during cellular respiration, specifically in the inner mitochondrial membrane. This process involves the pumping of protons across the membrane, creating an electrochemical gradient that drives ATP synthase to produce ATP from ADP and inorganic phosphate.
What is mitchells chemiosmotic hypothesis?
Mitchell's chemiosmotic hypothesis proposes that the energy needed for ATP synthesis in mitochondria is generated by the electrochemical gradient of protons across the inner mitochondrial membrane. This gradient is established by the pumping of protons out of the mitochondrial matrix during electron transport chain reactions. The protons then flow back into the matrix through ATP synthase, driving the production of ATP.
Synthesis of ATP by chemiosmotic mechanism occurs during?
Synthesis of ATP by chemiosmotic mechanism occurs during oxidative phosphorylation in the inner mitochondrial membrane. Protons are pumped across the membrane by the electron transport chain, creating a proton gradient. ATP synthase then uses this gradient to generate ATP from ADP and inorganic phosphate.

The difference between oxidative phosphorylation and chemiosmotic coupling?
Oxidative phosphorylation is the process in cellular respiration where ATP is produced from the transfer of electrons along the electron transport chain coupled with the pumping of protons across the inner mitochondrial membrane. Chemiosmotic coupling refers to how the proton gradient generated by the electron transport chain drives ATP synthesis by ATP synthase through the flow of protons back across the inner membrane. In essence, oxidative phosphorylation is the overall process, while chemiosmotic coupling is a specific mechanism within this process that connects electron transport and ATP synthesis.
Which molecules are responsible for creating a chemiosmotic gradient?
Protons (H+) are the main molecules responsible for creating a chemiosmotic gradient across biological membranes. In cellular respiration, the electron transport chain pumps protons across the inner mitochondrial membrane, creating a gradient that drives ATP synthesis through ATP synthase.

What is the source of the energy that produces the chemiosmotic gradient in mitochondria?
The energy that produces the chemiosmotic gradient in mitochondria is derived from the electron transport chain. As electrons are transferred along the chain, protons are pumped across the inner mitochondrial membrane, creating a proton gradient. This gradient is then used by ATP synthase to generate ATP from ADP and inorganic phosphate.
What does MDG stand for?

What requires oxygen in the generation of ATP?
Mitochondria.

Where do light dependent reactions occurr?
The light-dependent reactions take place on the thylakoid membranes in the chloroplasts. It takes place here because the membranes have the proteins for an electron transport chain as well as a natural barrier to make a chemiosmotic barrier that can be utilized by the ATP synthase to produce ATP.
