Throughout the electron transport chain many reactions occur. What happens to NADH eventually? NADH is reduced NADH is not used in ETC. ONADH remains unchanged in ETC but is used later. ONADH is oxidized

Which one of the following best describes the electron transport chain? Electrons are passed from one carrier to another releasing a little energy at each step Electrons are pumped across a membrane by active transport Glucose is broken down to a three-carbon compound in preparation for the citric acid cycle Hydrogen atoms are added to CO2 to make an energy-rich compound Acetyl CoA is fully oxidized to CO2
