Dec 07, 2021 · The electron transport chain is a series of molecules that accept or donate electrons easily. By moving step-by-step through these, electrons are moved in a specific direction across a membrane. The movement of hydrogen ions are coupled with this. This means that when electrons are moved, hydrogen ions move too. Anne ⭐ Answeregy Expert
Dec 20, 2021 · The two molecules generated by the Krebs cycle that pass their high-energy electrons to the electron transport are NADH and FADH2. Explanation: The kreb's cycle gives NADH and also the another hydrogen carrier which is termed as FADH2.During the process of the electron transport chain, one NADH gives rise to electrons and also the hydrogen ions, …
Jun 05, 2012 · coenzymes NAD and FAD that are attached to the cristae of the mitochondria. The reduced NAD and FAD donate the electrons of the hydrogen atoms they are carrying to the first molecule in the...
Removing 2 H atoms from substrate, delivering 2 electrons and one proton to NAD+, and releasing the remaining proton to the surrounding solution What is the process in which high energy electrons transferred from the substrate to NAD+ are passed down the ETC to oxygen, therefore powering ATP synthesis
The electron transport chain is also called the Cytochrome oxidase system or as the Respiratory chain. The components of the chain include FMN, Fe–S centers, coenzyme Q, and a series of cytochromes (b, c1, c, and aa3). The energy derived from the transfer of electrons through the electron transport chain is used to pump protons across ...
The production of ATP is coupled to the transfer of electrons through the electron transport chain to O2. The overall process is known as oxidative phosphorylation. Protons flow down their electrochemical gradient through the membrane-bound ATP synthase. The flow of protons through the ATPase allows the enzyme to synthesize ATP.
ATP is generated as a result of the energy produced when electrons from NADH and FADH2 are passed to molecular oxygen by a series of electron carriers, collectively known as the electron transport chain ( ETC). The electron transport chain is also called the Cytochrome oxidase system or as the Respiratory chain.
The electron transport chain is the final and most important step of cellular respiration. While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created. It has an important role in both photosynthesis and cellular respiration.
The NADH and FADH2 formed in glycolysis, TCA cycle and fatty acid oxidation are energy-rich molecules because they contain a pair of electrons that have high transfer potential.
Location of ETC. The respiratory chain is located in the cytoplasmic membrane of bacteria but in case of eukaryotic cells it is located on the membrane of mitochondria.
