What powers the proton gradient of positive ions in the stroma?
proton gradient
In which form does a cell temporarily store the energy from electrons?
As a proton gradient
Is hydrogen gradient across the mitochondrial inner membrane a cellular energy currency?
ATP molecules are essentially cellular energy currency. The hydrogen gradient (or proton gradient as it is technically called) is responsible for the functioning of a protein complex called ATP synthase which in turn is responsible for the synthesis of ATP molecules. Therefore, the proton gradient is the driving force for the synthesis of ATP molecules.
ATP synthase works by means of?
a proton gradient across the inner mitochondrial membrane
What situations does not represent a transformation of one type of energy to another?
the coupling of ATP hydrolysis to the production of a proton gradient across a membrane by a proton pump
What powers the proton gradient of positive ions in the stroma?
proton gradient
Which of the following is an inhibitor of the inner mitochondrial proton gradient?
Dinitrophenol
Synthesis of ATP via a proton gradient is called?
Chemiosmosis (involves the pumping of protons through special channels in the membranes of mitochondria from the inner to the outer compartment. The pumping establishes a proton gradient).
In which form does a cell temporarily store the energy from electrons?
As a proton gradient
The actual transport of protons by the proton pump is mediated by a transmembrane protein which undergoes a change in its?
If the protein is pumping protons, there should be an electrical gradient across the membrane as well as a proton concentration gradient.
The difference between oxidative phosphorylation and chemiosmotic coupling?
oxidative phosphorylation does not involve with the respiratory complex in the inner mitochondria membrane. Oxidative phosphorylation useful in generate the production of ATP from the proton gradient or proton motive force. Chemiosmotic coupling invilve the manner of ETC on how its create the proton gradient and the proton gradient is indirectly directed with the production of ATP.The proton gradient causes the conformational change of tigthly binding of ATP to open binding ATP .Then ATP can be released and be used to the metabolic cell needs and translocate the ATP to cytoplasm that can be used to phosphorylate substrate.
The creation of a proton gradient occures during which biochemical pathway?
All of the following are associated with chemiosmosis EXCEPT Answer creation of a proton gradient. beta-oxidation. phosphorylation of 34 molecules of ADP. oxidative phosphorylation. ATP synthase.

Therefore, the proton gradient is the driving force for the synthesis of ATP molecules.
ATP synthase works by means of?
a proton gradient across the inner mitochondrial membrane
What energy helps to reform ATP from ADP and phosphate?
A proton (H+) gradient
What situations does not represent a transformation of one type of energy to another?
the coupling of ATP hydrolysis to the production of a proton gradient across a membrane by a proton pump
How is proton gradient established?
A proton gradient is established with an electron transport chain, where energy from electrons is donated from an high-energy source (such as food) to provide intracellular enzymes the energy to pump protons across an impermeable membrane in order to form a region with a high concentration of protons. Hope this helps! :)
