What else can I help you with?
Electron transport chain pumps hydrogen ions to what space?
mitochondria inner membrane
When electrons are transported to enzyme complex 1 where is a proton transported?
Proton transport occurs in Complex I of the electron transport chain within the mitochondria. As electrons move through the complex, protons are pumped from the mitochondrial matrix into the intermembrane space, creating a proton gradient that drives ATP synthesis.
Which ion ends up in the intermembrane space during electron transport chain?
Protons (H+ ions) end up in the intermembrane space during the electron transport chain. These protons are pumped across the inner mitochondrial membrane from the matrix to the intermembrane space as electrons flow through the electron transport chain.
Where do the reactions of the electrons transport chains occur?
In the inner membrane of the mitochondria.
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."
Describe the pathway of electrons from the time they enter the intermembrane space of the mitochondrion to the time they are returned to the inside of the mitochondrion?
Electrons enter the intermembrane space of the mitochondrion through Complex III in the electron transport chain. They then travel to Complex IV, where they reduce oxygen to form water. Once the electrons have been used in the transport chain, they are returned to the inside of the mitochondrion by pumping protons out of the matrix during oxidative phosphorylation, creating a proton gradient that drives ATP synthesis.
H ions build up in what space?
as the electrons pass down the electron transport chain, h+ ions build up in the _____ space?
The energy released in the mitochondrial electron transport chain is used to transport protons into the?
The energy released in the mitochondrial electron transport chain is used to transport protons into the intermembrane space of the mitochondria. This creates a proton gradient that is utilized by ATP synthase to produce ATP through oxidative phosphorylation.
What is the function of intermembrane space?
The intermembrane space plays a role in cellular respiration by providing a location for the transport of electrons and protons during the production of ATP. It also helps create a proton gradient across the inner mitochondrial membrane, which drives ATP synthesis.
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.
What happen when electrons are passed down the electrons transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
Where do H ions build up in as electrons pass down the electron transport chain?
H+ ions build up in the intermembrane space of the mitochondria as electrons pass down the electron transport chain. This forms an electrochemical gradient that drives ATP production through ATP synthase.
