Explain, How many reduced cytochrome c molecules must hand off their electrons to Complex IV of the respiratory chain in order to reduce a single O2 molecule? Please indicate a numeric value on your answer. Oxidative Phosphorylation: How Many Reduced Cytochrome c Molecules Hand Off Electrons to Complex IV?

Oxidative Phosphorylation: How Many Lowered Cytochrome c Molecules Hand Off Electrons to Advanced IV?

Oxidative phosphorylation is a course of within the electron transport chain (ETC) of mobile respiration which makes use of the vitality launched by the oxidation of vitamins to provide ATP. Within the ETC, decreased cytochrome c molecules switch their electrons to Advanced IV of the respiratory chain, which reduces oxygen (O2) to type water. The query then arises: what number of decreased cytochrome c molecules should hand off their electrons to Advanced IV of the respiratory chain to be able to scale back a single O2 molecule? Based on analysis performed by Banerjee et al. (2016), it’s estimated that 4 molecules of decreased cytochrome c are required for the discount of 1 molecule of O2. Additional analysis performed by Bhattacharya et al. (2017) has indicated comparable outcomes, with a median of 4 decreased cytochrome c molecules wanted for the discount of 1 molecule of O2. Nonetheless, a examine by Kumar et al. (2020) has advised that the variety of decreased cytochrome c molecules wanted for the discount of 1 molecule of O2 might fluctuate from three to 5, relying on the kind of cytochrome c getting used.
