Cell Respiration - 2 Aerobic and Anaerobic Respiration Pathways Oxidation-Reduction Reactions in Cell Respiration The oxidations of fuel molecules in aerobic cell respiration use specialized electron carrier molecules, most of which in eukaryotic organisms are located in the membranes of the mitochondria. These electron transport molecules gain and lose electrons at specific energy levels. This is very similar to the electron transport molecules used in photosynthesis. One of the most important of the electron transport molecules in cell respiration

Unformatted text preview: is NAD + . Electrons are passed through an electron transport chain to form ATP by chemiosmosis, a process sometimes called oxidative phosphorylation or electron transport phosphorylation. Not all of the ATP produced during cell respiration is by chemiosmosis. Some ATP is also synthesized by a direct transfer of phosphate from a substrate molecule to ADP. This process is called substrate-level phosphorylation. We will discuss this more when we do the details of the cell respiration pathways....
