Oxioreductase enzyme reactions

Référence de la vidéo 11938239
Oxioreductase enzyme reactions. Animation showing the reactions that occur on an oxioreductase enzyme (green) with two binding sites. One of these binding sites is for a substrate (blue) in a reduced state with an attached proton (H), while the other is for a coenzyme (yellow) in its oxidized state. This coenzyme is nicotinamide adenine dinucleotide (NAD), the molecular structure of which is shown at left. The transfer of electrons from the substrate to NAD is accompanied by the transfer of the proton, resulting in the reduced form NADH. The redox reactions catalyzed by oxidoreductases are an important step in several key metabolic reactions, including cellular respiration and oxidative phosphorylation. An enzyme is a biological catalyst, increasing reaction rates without itself reacting or changing. For this animation with labels, see K004/4114.
