WebSep 17, 2014 · Electrons flow from the anode to the cathode through an external wire. A common galvanic cell is the Daniell cell, shown below. The Zn (s) gives up its electrons to form Zn²⁺ (aq) ions. The electrons remain … As electrons move through the electron transport chain, they go from a higher to a lower energy level and are ultimately passed to oxygen (forming water). Energy released in the electron transport chain is captured as a proton gradient, which powers production of ATP by a membrane protein called ATP … See more The reactions that allow energy to be extracted from molecules such as glucose, fats, and amino acids are called catabolic reactions, meaning that they involve breaking a larger molecule into smaller pieces. For … See more Cellular respiration involves many reactions in which electrons are passed from one molecule to another. Reactions involving electron … See more Like other chemical reactions, redox reactions involve a free energy change.
