سؤال

ليش ال fluoroacetate يعتبر سام شنو السبب ؟
المرحلة الخامسة | The Fifth Stage
سؤال ليش ال fluoroacetate يعتبر سام شنو السبب ؟
لان ال fluoroacetyl-CoA راح يتحد وية oxaloacetate حتى يكون fluorocitrate والي راح يسبب تثبيط لل aconitase ( الانزيم الي يحول ال Citrate الى isocitrate ) بالتالي راح يصير عندي تراكم لل citrate لان متحول .
There are three isoenzymes of isocitrate dehydrogenase. One, which uses NAD+, is found only in cytosol . The other two use NADP+ and are found in mitochondria and the cytosol

🔴 التفاعلات الخاصة بدورة كريبس ( الستريك اسد )

1. Acetyl-CoA + oxaloacetate --> citrate ( citrate synthase )

2. citrate --> isocitrate ( aconitase )

3. isocitrate --> oxalosuccinate ( H+ ) --> α–ketoglutarate ( سحبنا مجموعة كاربوكسيل ) ( isocitrate dehydrogenase )

4. α-Ketoglutarate --> succinyl-CoA ( α-ketoglutarate dehydrogenase )

5. Succinyl-CoA --> succinate ( succinate thiokinase )

6. succinate --> fumarate ( succinate
dehydrogenase )

7. fumarate --> L-malate ( fumarase )

8. Malate --> oxaloacetate ( malate dehydrogenase )
المرحلة الخامسة | The Fifth Stage

دورة كريبس راح تنطيكم 3 NADH و وحدة FADH

NADH = 2.5 ATP ( كل وحدة )
FADH = 1.5 ATP ( كل وحدة )

2.5 * 3 = 7.5 ATP

7.5 + 1.5 = 9 ATP
