ATP synthase works by means of?
a proton gradient across the inner mitochondrial membrane
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.
What powers the proton gradient of positive ions in the stroma?
proton gradient
What is responsible for pumping protons out of the mitochondrial matrix?
The inner mitochondrial membrane is impermeable to protons on its own, so the energy of the proton gradient is stable. This means that energy is needed to make the protons go somewhere, thereby continuing the electron transport system.
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.
In medicine what does a Proton Pump Inhibitor do?
A proton-pump inhibitor's main purpose is a reduction in the production of gastric acid. The inhibitor is used in a variety of treatments for conditions such as Dyspepsia, Eosinophilic esophagitis, and Barrett's esophagus.
Similarities between photophosphorylation and oxidative photophosphorylation?
The chemiosmosis theory postulates that living cells produce ATP from a proton gradient across a membrane by an enzyme called ATP synthase. Animals generate this proton gradient with the mitochondrial electron transport chain. When reductants (NADH, FADH2) give up their electrons to the electron transport chain, the electrons move to increasingly stronger oxidizing agents, using the released energy to pump protons across the mitochondrial inner membrane. Plants, however, generate the proton gradient directly with the photosystems and the photosynthetic electron transport chain. When the photosystem becomes excited, water is split into protons, oxygen and electrons. The electrons are then passed into the photosynthetic electron transport chain, which is analogous to the mitochondrial electron transport chain in that it also uses the energy of the oxidation reactions to pump protons across the thylakoid membrane. The end result is the same, however, because the proton gradient generates proton motive force, which is then used to synthesize ATP with ATP synthase.
What is a proton pump inhibitor?
The proton pump inhibitors are a group of drugs that reduce the secretion of gastric (stomach) acid.
Should you take a proton pump inhibitor and H2 blocker together?
yes
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
A prescription for a proton pump inhibitor would be written for a patient having this disorder?
