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.
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.
The movement of hydrogen ions across a mitochondrial membrane.
Protons (H) are pumped across the inner mitochondrial membrane to create a proton gradient, which is used to generate ATP through a process called oxidative phosphorylation. This ATP is the main source of energy for the cell.
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.
Protons (H+ ions) move across the inner mitochondrial membrane through ATP synthase to synthesize ATP during chemiosmosis. This process is driven by the proton gradient that is established during electron transport chain reactions.
The first electron carrier that pumps hydrogen ions during cellular respiration is NADH dehydrogenase (complex I) in the electron transport chain. It pumps hydrogen ions across the inner mitochondrial membrane from the matrix to the intermembrane space.
In mitochondria, hydrogen ions (protons) are actively pumped into the intermembrane space from the mitochondrial matrix during the electron transport chain process. This occurs primarily through the action of complexes I, III, and IV, which utilize the energy released from electron transfers to move protons across the inner mitochondrial membrane. The accumulation of protons in the intermembrane space creates a proton gradient, which drives ATP synthesis through ATP synthase as protons flow back into the matrix.
An area of the inner mitochondrial membrane becomes positively charged as a result of the electron transport chain process during cellular respiration. During this process, protons are pumped across the inner membrane, creating an electrochemical gradient with a higher concentration of protons in the intermembrane space compared to the mitochondrial matrix. This results in a positively charged intermembrane space and a negatively charged matrix.
Protons (H+ ions) are pumped across the inner mitochondrial membrane during electron transport in the electron transport chain (ETC). This creates a proton gradient that is used to generate ATP via ATP synthase.
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.

The mitochondrial intermembrane space becomes acidic during mitochondrial electron transport due to the pumping of protons from the matrix across the inner membrane to the intermembrane space by complexes I, III, and IV of the electron transport chain. This forms an electrochemical gradient used to generate ATP through ATP synthase.
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.
Protons are actively pumped across the inner mitochondrial membrane from the mitochondrial matrix to the intermembrane space during the first electron transport chain. This creates a proton gradient that is essential for ATP production.
