1The main enzymes targets for regulation in the krebs cycle are:
- Acitrate synthase and fumarase
- BAconitase, succinate dehydrogenase and fumarase
- Ccitrate synthase, isocitrate dehydrogenase and alpha ketoglutarate dehydrogenase
- Disocitrate dehydrogenase and alpha ketoglutarate dehydrogenase
2Sodium fluoroacetate is...
- Apart of the krebs cycle
- Ban enzyme in the krebs cycle
