السلام عليكم ورحمة الله وبركاتة .
ملف الفلاش التالي يحتوي على معلومات جميلة عن TCA Cycle,citric acid cycle or Krebs cycle
WIDTH=710 HEIGHT=480
وهذه صوره توضح تسلسل التفاعلات بالصيغة الكيميائية و الانزيمات المحفزه و نواتج التفاعل .

The TCA cycle showing enzymes, substrates and products. The abbreviated enzymes are: IDH = isocitrate dehydrogenase and a-KGDH = a-ketoglutarate dehydrogenase. The GTP generated during the succinate thiokinase (succinyl-CoA synthetase) reaction is equivalent to a mole of ATP by virtue of the presence of nucleoside diphosphokinase. The 3 moles of NADH and 1 mole of FADH2 generated during each round of the cycle feed into the oxidative phosphorylation pathway. Each mole of NADH leads to 3 moles of ATP and each mole of FADH2 leads to 2 moles of ATP. Therefore, for each mole of pyruvate which enters the TCA cycle, 12 moles of ATP can be generated.
أتمنى أن الموضوع مفيد :)
