Electron transport chain pumps hydrogen ions to what space?
mitochondria inner membrane
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."
The energy given up by electrons as they move through the electron transport chain is used to?
A good portion of the energy from the electron movement is used to pump H+ across a gradient.
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.

H plus ions build up in the?
intermembrane space
How is energy in the electron transport system temporarily stored?
By pumping protons into intermembrane space
What part of the mitochondria stores a high concentration of H plus ions?
The intermembrane space.
If Hydrogen ion concentration in the intermembrane space and the matrix reach equilibrium?
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.
When electrons are transported to enzyme complex 1 where is a proton transported?
To the intermembrane space
What ion is pumped across the inner membrane in the ETC?
Protons are pumped across the inner membrane into the intermembrane space.
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?
The electrons move
What are the parts of chloroplast?
