The reactions of the electron transport chain (ETC) occur in the inner mitochondrial membrane of eukaryotic cells. This membrane houses the protein complexes and electron carriers that facilitate the transfer of electrons from NADH and FADH2 to oxygen. As electrons move through the chain, protons are pumped into the intermembrane space, creating a proton gradient that drives ATP synthesis through ATP synthase. In prokaryotes, the ETC occurs in the cell membrane since they lack mitochondria.

What reactions occur in the cristae of the mitochondria?
The cristae of the mitochondria are the sites for the electron transport chain and oxidative phosphorylation. These reactions involve transferring electrons along the chain and using the energy released to pump protons across the inner mitochondrial membrane, creating a proton gradient that drives ATP synthesis.
Which reactions of aerobic respiration occur in the inner mitochondrial membranes?
The electron transport chain and oxidative phosphorylation occur in the inner mitochondrial membrane of cells during aerobic respiration. These processes involve transferring electrons through a series of protein complexes to generate ATP, the cell's primary energy source. The inner mitochondrial membrane provides a specialized environment for these reactions to occur efficiently.
Does the light independent reactions of the Calvin cycle occur in the thylakoids?
In photosynthesis, the the electron transport chain is part of the light dependent reactions. The "light independent reactions" are the Calvin-Benson cycle and do not include an electron transport chain, but the Calvin Cycle cannot proceed without the ATP and NADPH produced during the light reactions.
What does electron transport chain occur in?
the mitochondria.
Where do the reactions of the electrons transport chains occur?
In the inner membrane of the mitochondria.
Where do the reactions of each electron transport chain occur?
In the inner membrane of the mitochondria.
Where do the reactions of the electron transportation chain occur?
In the inner membrane of the mitochondria.
Where do the reactants of the electron transport chain occur?
In the inner membrane of the mitochondrial organelle.
Where does cyclic electron transport occur?
Cyclic electron transport occurs in the thylakoid membrane of chloroplasts during the light reactions of photosynthesis. It involves the flow of electrons through the photosynthetic electron transport chain to generate ATP without the production of NADPH.
Can the electron transport chain occur without the Krebs cycle?
Yes, the electron transport chain can occur without the Krebs cycle. The electron transport chain generates ATP by transferring electrons through a series of protein complexes in the inner mitochondrial membrane, regardless of whether the electrons come from the Krebs cycle or other sources.
Where does the eletron transport chain occur?
Inner membrane of the mitochondria and thylakoid membrane of chloroplasts.
The reactions that convert the energy in sunlight into chemical energy of ATP and NADPH?
The reactions that convert the energy in sunlight into chemical energy of ATP and NADPH are called the light-dependent reactions of photosynthesis. These reactions occur in the thylakoid membranes of chloroplasts and involve the absorption of light by chlorophyll and other pigments to drive the production of ATP and NADPH through a series of electron transport chain reactions.
