no carbon dioxide isn't produced during photosynthesis :)
The final reduced species in the electron transport chain is water. Oxygen is the final electron acceptor in the chain, and it is reduced to form water.
During oxidative phosphorylation, which is part of the electron transport chain, a total of 6 water molecules are formed when oxygen is reduced to form water at the end of the chain.
In the electron transport chain Oxygen is the final electron acceptor. Also the Oxygen accepts 2 Hydrogen ions, making water in the process. The dissapearance of Oxygen shows that the electron transport chain is working and that Oxygen is doing its job.
water is made during the electron transport chain (etc) phase.
The oxygen molecules that you breathe are actually used in the last part of aerobic respiration. They are the final electron acceptors in electron transport chain.
The final reduced species in the electron transport chain is water. Oxygen is the final electron acceptor in the chain, and it is reduced to form water.
oxygen is reduced to water in respiration, specifically in the electron transport chain
Electron transport chains are present in mitochondria. The products of the electron transport chains are energy in the form of thermodynamics and water which is reduced from oxygen.
The final acceptor of electrons and hydrogens in the electron transport chain is oxygen. Oxygen is reduced to form water, which is essential for cellular respiration to continue efficiently.
O2 ADDED: Not O2, but one atom of oxygen.
In aerobic respiration, the molecule that is reduced is oxygen (O₂). During the process, oxygen acts as the final electron acceptor in the electron transport chain, where it combines with electrons and protons to form water (H₂O). This reduction of oxygen is crucial for the efficient production of ATP, the energy currency of the cell.
Protons fall down their concentration gradient through the ATP-synthase and are picked up by oxygen, along with electrons, to make water. So, ATP and water " comes out " the electron transport chain.
Glucose. Glucose is oxidized and oxygen is reduced here.
During oxidative phosphorylation, which is part of the electron transport chain, a total of 6 water molecules are formed when oxygen is reduced to form water at the end of the chain.
Hydrogen ions are pumped into the mitochondrion during electron transport. Oxygen is the final acceptor of the electron resulting in the formation of water.
In aerobic respiration, the final electron acceptor is (usually) oxygen. Sometimes it can be sulfur or nitrogen in the absence of oxygen (as in extreme environments) in extremophiles.
1)ATP formed as electrons pass along transport chain 2)oxygen is terminal electron acceptor / accepts electrons from electron transport chain 3)electrons cannot be passed along electron transport chain if no O2 to accept them 4)forms H2O / accepts H+ from reduced NAD/FAD / oxidises reduced NAD/FAD
