If Hydrogen ion concentration in the intermembrane space and the matrix reach equilibrium?
Kdel4053
If hydrogen ion concentration in the inter membrane space and matrix of a mitocondria reach equilibrium then ATP synthase, which relies on a high concentration of hydrogen ions in the intermembrane space will work slower, letting less hydrogen ions into the matrix, while proteins in the electron transport chain pump hydrogen ions into the intermembrane space at a faster rate, destroying the equilibrium.

What is the name and function of the protein channel where hydrogen ions escape into the matrix of the mitochondrion?
ATP synthase; to add a phospate to ADP
What is spike method in chemical analysis?
In chemistry, the spike method, more often called the addition method, is used to find the concentration of an analyte in a complex matrix. Examples of such matrices would be soil samples or biological fluids.
What is the diffence between a hydrogen fuel cell and a hydrogen combustion engine?
A hydrogen combustion engine is like the engine in your car. Hydrogen and oxygen enter a combustion chamber, ignite, and form a ball of hot vapour (steam) which moves a piston that rotates a crankshaft. Alternately a hydrogen combustion engine could be a rocket or jet engine where the burning fuel exhausts the combustion chamber as vapour (steam again) and impacts a forward motion to the engine by the mass discharge. A fuel hydrogen cell is more like a battery. Hydrogen and oxygen react in a catalyst matrix that allows the process to continue at a fixed rate. Like most chemical reactions this involves the movement of electrons to create positive and negative reactant ions. The flow of electrons is conducted to an electrical system as power. Water is still the byproduct.
When you mix matrix hair color with matrix solite cream developer does t have to be in a plastic bowl?
No. Glass can be used as well.
Where does the Krebs cycle occurs?
The Krebs cycle occurs in the mitochondrial matrix of the cell.The kreb cycle takes place in the matrix of the mitochondria.
What are the directions of hydrogen flow during synthesis of ATP?
From the intermembrane space to the inner matrix
What portion of the mitochondria has the lowest pH?
According to another answer to a similar question here on this site, "The intermembrane space has the lowest pH, highest concentration of H+, due to the gradient created by the electron transport chain."
What is oxidative phosphorylation and what is its purpose?
Oxidative phosphorylation occurs in order to produce energy in the form of ATP. It occurs after chemiosmosis, in which a concentration gradient of hydrogen ions is created in the mitochondria between the matrix and the intermembrane space. As the hydrogen ions flow across this gradient, ADP and Pi are combined and ATP is produced. Hope this helps!
What drives the ATP synthase reactions that produced ATP?
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.
Which of the following processes involved in cellular respiration has a positive Gibbs Free energy?
The pumping of hydrogens from the mitochondrial matrix to the intermembrane space
In what organelle does the electron transport chain function?
The electron transport chain converts energy stored in hydrogen ions and various other substances formed in early cellular respiration to produce high energy ATP in mitochondria. Mitochondria contain both an inner and an outer membrane, and it is along the inner membrane that the actual reactions of the chain occur. Inside the inner membrane a surplus of hydrogen ions is created that produces a concentration gradient across the membrane to the intermembrane space. This gradient causes a force that pushes hydrogen ions out of the innermost matrix and into the intermembrane space. This exchange occurs through special proteins called ATP synthase that convert low energy ADP into high energy ATP whenever a hydrogen ion is sent through one. When all is said and done, the excess electrons and hydrogen are bonded to oxygen to form water molecules.

Equilibrium?
What is the structure of the mitochondria?
The structure of the mitochondria include the inner mitochondrial membrane, the outer mitochondrial membrane, the intermembrane space, the cristae, and then the mitochondrial matrix. Click on the related link for a detailed description on the structure of the mitochondria.
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 causes the h ions in the intermembrane space to move through the channels in the membrane and out the into the matrix?
The energy of the high energy molecules used for every time 2 high energy electrons move down the chain causes the H+ ions to move to the matrix.
The electron transport process makes water and ATP and is sometimes called?
To understand this, you have to realize some things about mitochondria - 1) its inner membrane is not permeable for H+(protons). 2) the system is set up like that ATPase (the ATP-producing enzyme) is located in inner mitochondrial membrane and it produces ATP by protons flowing through it from intermembrane space of mitochondria (outside the inner membrane, NOT in mitochondrial matrix) to matrix. To do that, there has to be high amount of protons in intermembrane space; then, the protons flow through the ATPase to mitochondrial matrix by themselves, simply by their concentration gradient.Now, logically, without nothing, the concentration gradient of the protons would deplete itself through the ATPase in very quickly. That is where the electron transport chain comes in - the electron transport chain basically uses up the energy of electrons taken from food, = reduced NAD+, the NADH. Each NADH carries an electron (or it is two electrons, not sure here) and gives it to the electron transport chain. And in the chain, an energy of the electron is withdrawn and used for pumping of protons to the intermembrane space. Energy of each electron going through the electron transport chain provides for pumping of 10 protons together. For imagination, this is enough for an ATPase to produce about 3 molecules of ATP.
What job does the electron transport chain accomplish in order to drive the formation of ATP?
The proteins in the electron transport chain pump protons from the matrix of the mitochondria to the intermembrane space, thus establishing an electrochemical gradient
