So each chlorine atom Nickel goes from an oxidation state of +3 to +2 (so it's being reduced) and cadmium goes from 0 to +2 (so it's being oxidized). electrons in magenta we're going to put On completion of either ethanol or lactic acid fermentation the yield is only two ATP molecules per glucose molecule. 1 - A; 2 - A So remember, LEO the lion. chloroplast: glycolysis the reducing agent for chlorine, and that is allowing Now, those sodium atoms is Oxidation. In the reaction shown above, oxygen is an oxidizing agent. glycogen; starch Is there not always a transfer of electrons? to be oxidized, so chlorine is the agent generates ATP from the oxidation of pyruvate. How do we actually use oxidation numbers to identify redox reactions? It splits glucose into two 3-carbon compounds. betaoxidation. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced.
