When a biological molecule is oxidized, the electrons are often captured by NAD, which is reduced to NADH. With that knowledge, identify if the substrate other than NADH or NAD in each reaction is being oxidized or reduced Diphosphoglycerale + NADH Glyceraldehyde phosphate + NAD Reduced Oxidized Isocrate + NAD > alpha-ketoglutarale + CO NADH Pyruvate NADH-> Lactate NAD- Malate.

9. In the electron transport chain picture above, how do electrons move from protein complex I to protein complex II? 1. I need you to remember that "Q" is ubiquinone which gets reduced at proteins l & I, and oxidized at protein III. "Reduced" means gains electrons, "oxidized" means loses electrons. 2.
