Where does the etc occur in the mitochondrion?
The electron transport chain (ETC) occurs in the inner mitochondrial membrane of the mitochondrion. This membrane contains various protein complexes and electron carriers that facilitate the transfer of electrons derived from metabolic fuels, ultimately leading to the production of ATP through oxidative phosphorylation. The ETC is crucial for generating a proton gradient across the inner membrane, which drives ATP synthesis.
What occurs in the ETC during cellular respiration?
The high energy from the electron carriers NADH and FADH2 is passed to membrane-bound enzymes that use the energy to pump protons across the inner membrane into the inter-membrane space. The energy is gradually used by an entire "chain" of enzymes to establish a proton gradient across the inner membrane of the mitochondrion. This is where chemiosmosis takes place. Proton motive force generates ATP through the passive diffusion of protons through the enzyme ATP synthase, thus converting ADP and and inorganic phosphate group into high energy ATP molecules. These ATP molecules can drive other endergonic reactions in the cell.
Where are ETS enzymes located in the mitochondria?
ETS enzymes are located in the inner mitochondrial membrane of eukaryotic cells. They are part of the electron transport chain (ETC) that generates ATP through oxidative phosphorylation. The ETS enzymes transfer electrons from NADH and FADH2 to oxygen, producing a proton gradient across the inner mitochondrial membrane.
Where in the mitochondria does the ETC occur?
The electron transport chain (ETC) occurs in the inner mitochondrial membrane. It is comprised of a series of protein complexes embedded in the membrane, through which electrons are passed along to generate ATP.
What happens as electrons are passed along the ETC?
As electrons are passed along the electron transport chain (ETC), they release energy. This energy is used to pump protons across the inner mitochondrial membrane, creating a proton gradient. The flow of protons back across the membrane drives ATP synthase to produce ATP.

Where in the mitochondria is the proteins of the ETC located?
The proteins of the electron transport chain (ETC) are located in the inner mitochondrial membrane. This is where the series of complexes involved in electron transfer and ATP production are situated.

Where is the etc located in mitochondria?
The electron transport chain (ETC) is located in the inner membrane of the mitochondria.
How many protons are pumped out of the matrix when 2 electrons flow through the ETC complex?
For every pair of electrons that flow through the electron transport chain (ETC) complex, it results in the pumping of 2 protons out of the matrix. This proton pumping contributes to the establishment of an electrochemical gradient across the inner mitochondrial membrane, which is utilized to generate ATP through ATP synthase.
What happens as electrons are passed along the ETC?
As electrons are passed along the electron transport chain (ETC), they release energy. This energy is used to pump protons across the inner mitochondrial membrane, creating a proton gradient. The flow of protons back across the membrane drives ATP synthase to produce ATP.
What is location of ETC and chemiosmosis in photosynthesis and cellular respiration?
In photosynthesis, ETC and chemiosmosis occur in the thylakoid membranes of chloroplasts. In cellular respiration, these processes take place in the inner mitochondrial membrane. These locations are where the electron transport chain (ETC) pumps protons across the membrane, creating a proton gradient that drives ATP production through chemiosmosis.
When NADH passes its electrons to the ETC it is?
When NADH passes its electrons to the electron transport chain (ETC), it helps create a proton gradient across the inner mitochondrial membrane. This gradient is used by ATP synthase to generate ATP through oxidative phosphorylation.
Why does fadh2 produce fewer ATP molecules than nadh?
NADH produces 3 ATPs because it donates the proton at a "higher" location in the electron transport chain than does FADH2, which is why FADH2 produce only 2 ATPs. NADH and FADH2 donates electrons and protons into the electron transport chain.
Where in the mitochondrion does the electron transport chain?
The electron transport chain takes place in the inner mitochondrial membrane. This is where the series of protein complexes and molecules work together to generate ATP through electron transfer and proton pumping.
