CoachThe 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.

When is the electron transport chain carried out?
Plants, fungi, and animals are all eukaryotes and possess mitochondria, which is the site of the electron transport chain. Prokaryotes have no mitochondria and perform the electron transport chain across their cell membranes. Electron transport chain also occurs in thylakoid membrane of chloroplasts.
Where in the cell do electron transport chain occur?
The electron transport chain occurs in the inner mitochondrial membrane of eukaryotic cells and the plasma membrane of prokaryotic cells. It is the final stage of cellular respiration where electron carriers pass electrons along a series of protein complexes to generate ATP.
The electron transport chain occurs in which organelle?
The electron transport chain occurs in the inner mitochondrial membrane.
Where does the electron transport chain take place in the mitochondria?
The electron transport chain takes place in the inner mitochondrial membrane of the mitochondria. It consists of a series of protein complexes that transfer electrons and generate a proton gradient across the inner membrane, which is used to produce ATP through oxidative phosphorylation.
What does the electron transport the chain during cellular respiration?
it provides energy that powers the formation of atp
