The proton gradient produced by the electron transport chain powers ATP production. This process is called chemiosmosis, in which H+ ions from the thylakoid space (in mitochondria they are in the intermembrane space) pass through ATP synthase to areas of lower concentration (in chloroplasts, the stroma, and in mitochondria, the mitochondrial matrix). As they pass through ATP synthase, the catalytic knob of the ATP synthase is turned. The turning of this knob (which is powered by diffusion of H+ ions) powers the anabolic production of 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.

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.
ATP synthase catalyzes which of the following reactions?
ADP+Pi→ATP
Where in the chloroplast are ATP and NADPH formed during the light reactions?
The light dependent reactions take place in the thylakoid of the chloroplast. ATP is formed in the ATP synthase protein by the assistance of the hydrogen gradient produced in the electron transport chain.
Are nadph and ATP produced by the Calvin cycle?
Yes, they carry energy between the light reactions and the Calvin cycle. ADP is phosphorylated into ATP at the ATP synthase while NADP is reduced by the electrons in the transport chain (it then becomes NADPH).
What powers the ATP synthase enzyme in the light-dependent reactions of photosynthesis?
Photosynthesis is the process that plants convert solar energy into the energy stored in chemical bonds. This consists of two reactions, light dependent and light independent.
When ATP synthase in activated it adds a phosphate group to what molecule?
ATP synthase catalyzes the addition of a phosphate group to an ADP molecule. ADP + ATP synthase + P --> ATP + ATP synthase (ATP synthase on both sides of the equation indicates that, as an enzyme, it is not used up in the reaction.)
What drives the ATP synthesis reactions that produce ATP?
what are the products that coca cola sail
What is produced in light- dependent reactions?
In light dependent reactions ATP and NADPH are produced
What passes through ATP synthase and causes ATP molecules to be produced from ADP molecules?
The hydrogen ions ( protons; H+ ) that are falling down their concentration gradient from where they were pumped into the outer lumen of the mitochondria and falling through the ATP-synthase to synthesize ATP ( phosphorylate ) from ADP.
What spins to provide energy for adding a phosphate group to ADP?
The rotor part of the ATP synthase enzyme.
Chlorophyll is to the light reactions as is to the Calvin cycle. a. NADP plus b. carbon dioxide c. ATP d. ATP synthase e. RuBP?
Rubp
What causes ATP synthase to spin during ATP production?
The electron gradient created by the electron transport chain flows from the inner membrane space to the matrix through the ATP synthase which captures energy from the proton motive force to create lots of ATP in oxadative phosphorylation.
