Why are the electrons carried by FADH2 not as energy rich as those carried by NADH? FADH2 carries fewer high-energy electrons than NADH. OFADH2 is less negatively charged than NADH. OFADH2 has a lower phosphoryl-transfer potential than NADH. FADH₂ has a lower reduction potential than NADH. What is the consequence of this difference? Electrons flow from NADH to FADH2 before they are transferred to O₂. Electron flow FADH₂ to O, results in the production of more ATP than does electron flow from NADH. Electron flow from FADH₂ to O, pumps fewer protons than does electron flow from NADH. Electron flow from FADH, to O, consumes more free energy than does electron flow from NADH. A simple equation relates the standard free-energy change, AG", to the change in reduction potential, AE. AG=-FAE Then represents the number of transferred electrons, and F is the Faraday constant with a value of 96.48 kJ mol¹ V-¹.
