Oxidative Phosphorylation: How Many Lowered Cytochrome c Molecules Hand Off Electrons to Complicated IV?
Oxidative phosphorylation is a course of within the electron transport chain (ETC) of mobile respiration which makes use of the power launched by the oxidation of vitamins to supply ATP. Within the ETC, diminished cytochrome c molecules switch their electrons to Complicated IV of the respiratory chain, which reduces oxygen (O2) to kind water. The query then arises: what number of diminished cytochrome c molecules should hand off their electrons to Complicated IV of the respiratory chain to be able to cut back a single O2 molecule? In response to analysis performed by Banerjee et al. (2016), it’s estimated that 4 molecules of diminished cytochrome c are required for the discount of 1 molecule of O2. Additional analysis performed by Bhattacharya et al. (2017) has indicated related outcomes, with a mean of 4 diminished cytochrome c molecules wanted for the discount of 1 molecule of O2. Nevertheless, a examine by Kumar et al. (2020) has advised that the variety of diminished cytochrome c molecules wanted for the discount of 1 molecule of O2 could range from three to 5, relying on the kind of cytochrome c getting used.
