Does fermentation contains ETC?
Fermentation does not require the electron transport chain (ETC) as it does not rely on oxygen as the final electron acceptor. Instead, fermentation relies on substrate-level phosphorylation to produce energy in the absence of oxygen.
What procces in respiration happens last?
Electronic transport chain
What events take place within the mitochodrial membrane?
ETC---Electron transport chain
The final reduced species in the electron transport chain is?
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.
Does active transport involve respiration and fermentation?
The correct question is: Does respiration and fermentation involve active transport? Active transport is a fundamental process that is pertinent to many other cellular processes. In nature, matter wants to equilibrate, gases, molecules, and ions all want to homogenize. Active transport opposes this; it is the movement of ions, gases, and molecules from areas of low concentration to areas of high concentration. Active transport is the reason life has been described as seemingly violating the 2nd Law of Thermodynamics ( this is not actually the case) where the change in entropy of a system must increase after any process. In cellular respiration a chain of proteins is reduced by molecules made during glycolysis and the citric acid cycle. The electron that is handed off at the top of this electron transport chain of proteins is electrically attracted to the oxygen molecule housed in a protein at the end of the chain. The entire purpose of this flow of electrons is to power the active transport of protons from the cytoplasm to the inner mitochondrial membrane (or in the case of prokaryotes, from the exterior of the cell to the interior of the cell). The energy of this proton concentration gradient is then stored in molecules called ATP as the protons flow down the gradient and through an enzyme called ATP-synthase. Fermentation occurs in the absence of oxygen as the final electron acceptor of the electron transport chain. While fermentation does not involve the active transport of protons like respiration it does require the active transport of glucose. A higher concentration of glucose must be maintained within the confines of a cell than in the cells external environment. This is especially the case with bacteria and other prokaryotes that are not privileged like the intestinal cells of animals which our regularly surrounded by glucose. If you dig deep you will find that most cellular processes involve active transport in some direct or indirect way.
Is The electron transport chain recycled during fermentation?
No, NAD+ is
What type of cellular respiration does not have a Krebs cycle or an electron transport chain?
fermentation
Is water an end product of fermentation the Krebs cycle or the electron transport chain?
Water is a byproduct of the electron transport chain during cellular respiration. It is formed when oxygen combines with electrons and hydrogen ions to produce water molecules.
Does fermentation contains ETC?
Fermentation does not require the electron transport chain (ETC) as it does not rely on oxygen as the final electron acceptor. Instead, fermentation relies on substrate-level phosphorylation to produce energy in the absence of oxygen.
