From our free online course, “Cell Biology: Mitochondria”: [HOST]?utm_source=social&utm_med The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons Replays. The content you are trying to view is Not Authorized at this source. It was only intended for CenturyDowns. If you feel you have reached this page in error, The electron transport chain consists of a series of four enzyme complexes (Complex I – Complex IV) and two coenzymes (ubiquinone and Cytochrome c), which act as electron carriers and proton pumps used to transfer H + ions into the space between the inner and outer mitochondrial membranes (Figure \(\PageIndex{5}\)) (Category 3) Alternatively, PCA directly reduce the terminal electron acceptor. This may happen externally to the cell, or PCA may enter the cytoplasm and react with the terminal electron acceptor independently of the electron transport chain, as depicted. In this illustration, the arrows may represent direct reactions or ones In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step.

The electron transport chain (ETC) is a sequence of redox reactions that take place in eukaryotic cells’ inner mitochondrial membranes or prokaryotic cells’ plasma membranes. The steps of ETC process are as follows: NADH and FADH 2, which are synthesized in early phases of cellular respiration such as glycolysis, pyruvate oxidation,

This page titled The Electron Transport Chain is shared under a CK license and was authored, remixed, and/or curated by CK Foundation. At the end of the Krebs Cycle, energy from the chemical bonds of glucose is stored in diverse energy carrier molecules: four ATPs, but also two FADH 2 and ten NADH molecules. The Students can manipulate the ETC by changing different parameters like the wavelength of the light. Interactive models are another great way to provide students with a tactile way to explore the ETC. 2. Learning with Games and Activities. Games and activities can be highly effective and engaging tools for teaching students about the electron Figure 1: The third stage of cellular respiration uses the energy stored during the earlier stages in NADH and FADH 2 2 to make ATP. Electron transport chains embedded in the mitochondrial inner membrane capture high-energy electrons from the carrier molecules and use them to concentrate hydrogen ions in the intermembrane Wise loss of energy each time the electron is passed to a different cyto-chrome. Discuss with the class that the passage of electrons down a transport chain is necessary because the energy from the electrons in NADH cannot be transferred to oxygen in one reaction, because of the explosiveness of one reaction. The electron transport chain allows The electron transport chain (ETC) sends electrons through a series of proteins Proteins Linear polypeptides that are synthesized on ribosomes and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of amino acids determines the shape the polypeptide will take, The electron transport chain consists of four protein complexes (I-IV) and two mobile electron carriers (coenzyme Q and cytochrome c). II. Function of the Electron Transport Chain. The electron transport chain serves to transfer electrons from NADH and FADH2, generated during the citric acid cycle, to oxygen, the final electron acceptor
