Both NADPH and ATP are phosphorylated compounds, both are very important catabolic as well as anabolic processes. Topics. Meanwhile, in the electron transport chain, all of the NADH molecules are subsequently split into NAD+, producing H+ and a couple of electrons, too. Scientists have yet to identify what the optimal ratio is, let alone what the ramifications are when it's perturbed. For example, excessive consumption of alcohol would likely decrease the NAD+/NADH ratio within the cytoplasm, owing to excess conversion of NAD+ to NADH in order to oxidize the alcohol. But sometimes it’s referred to, colloquially, as just NAD (no plus), despite the little plus sign after it. In liver cells, for instance, the enzymes alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) utilize NAD+ as an oxidizing agent in order to breakdown ethanol from alcoholic drinks into a less toxic compound called acetate. Features Co-enzyme Co-factor; Definition: Co-enzymes are small, organic or metalloorganic, non-protein molecules that are as auxiliary for the specific action of an enzyme. NADH is a hydrogen ion carrier and i cant remember but it stands for something like nicotamide adeninose or something. When NAD+ is converted to NADH, it gains two things: First, a charged hydrogen molecule (H+) and next, two electrons. We’ll explain. Oxygen is not a requirement for Glycolysis. Cargo :-) The real business of NAD is ferrying the ‘energetic’ electrons that have been ripped out of sugar off to the electron transport chain. NADH is produced in the glycolysis and Krebs cycle. Look this up. This is believed to be due to the inability of NAD+ to cross the mitochondrial membrane (the "gateway" to the mitochondria), so changes in the cytoplasmic NAD+/NADH ratio have absolutely no effect on the mitochondria. It’s worth acknowledging that both NAD+ and NADH are key in the creation of ATP, as well as other biological processes, so it’s impossible to villainize or champion one over the other. The transformation of NAD+ to NADH. Oxidative phosphorylation: Reducing equivalent NADH, FADH 2 generated during glycolysis and the link between glycolysis and Kreb’s cycle are used to synthesize ATP by a process called oxidative phosphorylation (OP). In glycolysis and the Krebs cycle, NADH molecules are formed from NAD+. So the NADH to NAD ratio and the NAD pH to NADP plus ratio are things that are having real consequences as ratios and biochemistry that are dictating what's going on in our body.
