Cytochrome P450 Electron Sources (P450 Reductase or Adrenodoxin)

The video explains how cytochrome P-450 receives electrons to activate molecular oxygen, focusing on two systems: the mitochondrial adrena doxin reductase system and the microsomal P-450 reductase system. It details the electron transfer process from NADPH to FAD and further to the heme iron, highlighting the differences between the two systems based on their cellular location. The video also discusses the applications of these systems in processes like steroid synthesis.
