Hydrogen ions are pumped into the mitochondrion during electron transport. Oxygen is the final acceptor of the electron resulting in the formation of water.
What else can I help you with?
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.
Electron transport chain pumps hydrogen ions to what space?
mitochondria inner membrane
How is energy in the electron transport system temporarily stored?
By pumping protons into intermembrane space
What cellular compartment becomes acidic during mitochondrial electron transport?
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 the first electron transport chain in which direction are protons actively pumped?
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.
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.
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 inter membrane space?
The intermembrane space is the region between the inner and outer membranes of a mitochondrion. It plays a role in the production of ATP through the process of oxidative phosphorylation. Protons are pumped into the intermembrane space during electron transport chain reactions, creating a proton gradient that drives ATP synthesis in the mitochondria.
Where does the first electron carrier pump hydrogen ions?
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.
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.
How many protons in total are pumped into the intermembrane space of a mitochondria through the electron transport chain, if each complex individually receives 2 electrons?
12 protons
What ion is pumped across the inner membrane in the ETC?
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.
