1 The electron transport chain (ETC) is a shooting gallery Across all species, biological electron transport reactions are harnessed as a means to generate ATP and catalyze molecular transformations. While in eukaryotes, the specialized machinery of the ETC is housed in mitochondria, prokaryotic sys...
Cellular respiration involves four phases: glycolysis, the preparatory reaction, the citric acid cycle, and the electron transport chain. Electron transport chains are biochemical reactions that produce ATP, which is the energy currency of life. The generation of monomitochondrial ROS is a consequence ...
The Electron Transport System also called the Electron Transport Chain, is a chain of reactions that converts redox energy available from oxidation of NADH and FADH2, into proton-motive force which is used to synthesize ATP through conformational changes in the ATP synthase complex through a process...
reactions produce sugars needed for biosynthesis sugars can also be further degraded The Pentose Phosphate Pathway 14 The Tricarboxylic Acid Cycle also called citric acid cycle and Kreb’s cycle common in aerobic bacteria, free-living protozoa, most algae, and fungi major role...
reactions, with a small amount of free energy used at three points to transport hydrogen ions across a membrane. This process contributes to the gradient used in chemiosmosis. The electrons passing through the electron transport chain gradually lose energy, High-energy electrons donated to the chain...
The Electron Transport Chain The Electron Transport Chain February 19, 2003 Bryant Miles The citric acid cycle oxidizes acetate into two molecules of CO2 while capturing the electrons in the form of 3 NADH molecules and one molecule of FADH2. These reduced molecules contain a pair of electrons ...
