Is hydrogen gradient across the mitochondrial inner membrane a cellular energy currency?
Wiki User
∙ 14y ago
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 is the energy of the hydrogen ion gradient created across the inner mitochondrial membrane used to make?
electron transport chain
What is the role of hydrogen ion gradient used for in cellular respiration in the mitochondria?
The hydrogen ion gradient is used to drive ATP synthesis. 32 to 34 molecules of ATP are produced. The hydrogen ion gradient is the result of NADH in the electron transport system of the mitochondria.
What is the energy of hydrogen ion gradient created across the inner mitochondrial membrane used to make?
The hydrogen falls down its electrochemical gradient, from an area of high concentration to an area of lower concentration, through the ATP synthase and provides the force to power this synthase and synthesize ATP.
What will most likely happen if a toxin causes the hydrogen ion pump to stop moving h plus ions outside the mitochondrial?
No ATP production. Remember, the hydrogen ions pumped into the intermembrane space need to come down their concentration gradient through the ATP synthase to power ATP synthesis. No hydrogen ion buildup, no ATP synthesis.
What is the hydrogen ion gradient maintained by?
Carbon

When hydrogen ions are pumped from the mitochondrial matrix across the inner membrane and into the intermembrane space the result is?
Hydrogen ions are pumped through the membrane in the final stage of ATP generation in the electron transport chain. The ions pumped through the membrane create a gradient and cause the hydrogen to "want" to pass back through the membrane. They do so through the protein channels in the membrane and attaches a phosphate to adenosine diphosphate to make adenosine triphosphate.
What is chemiosis?
The process, in which energy stored in the form of a hydrogen ion gradient across a membrane is used to drive cellular work such as synthesis of ATP.
What phase of cellular respiration is the most energy stored?
Oxidative phosphorylation. When the hydrogen ions fall down their concentration gradient through the ATPase is when the most ATP is synthesized. Then oxygen and the hydrogen ions form water.
What will most likely happen if a toxin causes the hydrogen ion pump to stop moving h plus ions outside the mitochondrial?
No ATP production. Remember, the hydrogen ions pumped into the intermembrane space need to come down their concentration gradient through the ATP synthase to power ATP synthesis. No hydrogen ion buildup, no ATP synthesis.
What does Chemiosmosis involves .?
The movement of hydrogen ions across a mitochondrial membrane.
What will most likely happen if a toxin causes the hydrogen ion pump to stop moving H ions outside the mitochondrial membranes of the bird's cells?
Then there will be no build up of protons in the outer lumpen of the mitochondria. Without a heavy concentration of hydrogen ions ( protons ) there there will be no moment of hydrogen ions down their concentration gradient through the ATPase pump and no ATP generated.
What is the hydrogen ion gradient maintained by?
Carbon
Role of hydrogen atoms in aerobic cellular respiration?
In aerobic cellular respiration, hydrogen atoms are pumped into the intermembrane space of the mitochondria via a proton pump to create a concentration gradient. The flow of protons back into the matrix (call chemiosmosis) yields 32-34 molecules of ATP, which is where the bulk of the energy comes from in cellular respiration.
