part 2a: reduction and oxidation reactions PART 2A: RE REDOX react able to identify if a reaction is a REDOX reaction. REDOX ?Reduction (or the gaining of an electron) REDOXOxidation (or the loss of an electron) DUCTION AND OXIDATION REACTIONS ions will be a big part of our metabolic unit in this course. You will need to be In the scope of Bis2A, we will hold you accountable for recognizing the role of cofactors NAD+ and NADH in metabolic reactions as an oxidant or reductant, respectively. Rib-ADP RibADp Reduction Oxidation H NH2 NAD H NH2 NADH The half reaction above shows the reduction and oxidation of NAD NADH. This is a reversible reaction as denoted by the double arrow. From Part 1, you have seen how common NAD* is in metabolic pathways. Going from left to right, NAD becomes reduced (NAD' gains an electron and becomes NADH). Going from right to left NADH becomes oxidized (NADH loses and electron and becomes NAD*). From left to right, NAD* is gaining an electron. More specifically, NAD is gaining an electron from the other reactant in the reaction. 1. There are two reactants and two products in the reaction above (going from left to right) Products: Reactants .Explain what is happening to A in the reaction above using the terms Oxidation an Reduction.Explanation / Answer
There are two reactant and two products in the reaction above gaining from right
The reactants NAD+ + 2[H] Product is NADH + H+
The H atoms loose electrons (oxidation) and The NAD + (Oxidised) gain the electrons (reduction) and form NADH (reduced), A becomes B+ (oxidized), A is a strong reducing agent
