When hydrogen ions are pumped from the mitochondrial matrix across the inner membrane and into the intermembrane space the result is?

∙ 14y ago
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 does Chemiosmosis involves .?
The movement of hydrogen ions across a mitochondrial membrane.
What moves across the inner mitochondrial membrane to synthesize ATP during chemiosmosis?
protons
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 cell does chemiosmosis take place in?
Chemiosmosis occurs with those protons diffuse back, out of the intermembrane space, across the inner mitochondrial membrane, back into the matrix: as they do so, they pass through the membrane spannning ATP synthases which make ATP from ADP + Pi.
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.

Protons are pumped across the inner membrane into the intermembrane space.

Which accumulates in the inter membrane space of the mitochondrion during electron transport?
During electron transport in the mitochondrion, protons (H+) accumulate in the intermembrane space. This happens as electrons are transferred through the electron transport chain, creating a proton gradient across the inner mitochondrial membrane. This gradient of protons is later utilized by ATP synthase to generate ATP through oxidative phosphorylation.
Why is the difference in charge across the inner mitochondrial membrane important?
to produce ATP
How does the cell use the charge differences that build up across the inner mitochondrial membrane during cellular respiration?
The inner mitochondrial membrane contains enzymes known as ATP synthases.
ATP synthase works by means of?
a proton gradient across the inner mitochondrial membrane
What moves across the inner mitochondrial membrane to synthesize ATP during chemiosmosis?
protons
The transfer of high-energy electrons down the electron transport chain causes what to be transported across the mitochondrial membrane?
The electron movement causes H+ ions to be transported to the cystolic side of the mitochondrial membrane from the mitochondial matrix. This creates the electrochemical gradient that is used to generate chemical energy (ATP from ADP)
What is the energy of the hydrogen ion gradient created across the inner mitochondrial membrane use 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.
