第三节微生物产能代謝 生物氧化 生物氧化的形式包抬某物质与氧结合、脱 氨或脱电子三种 生物氧化的功能为 产能(ATP)、产还原力H和产小分子中 间代谢物 Organic molecule NAD coenzyme that includes two Oxidized organic (electron carrier) NADH+H*(proton) hydrogen atoms molecule (reduced electron carrier Oxidation Figure 5.9 Representative biological oxidation. Two electrons and two proton (altogether equivalent to two hydrogen atoms)are transferred from an organic substrate molecule to a coenzyme, NAD. NAD actually receives one hydrogen atom and one electron, and one proton is released into the medium. NAD+ is reduced to NADH, which is a more energy-rich molecule第二节 微生物产能代谢 一． 生物氧化 生物氧化的形式包括某物质与氧结合、脱 氢或脱电子三种 生物氧化的功能为： 产能（ATP）、产还原力[H]和产小分子中 间代谢物
