Describe the process that occurs at the electron transport chain and the process of chemiosmosis in order to produce ATP; including name the components of the ETC identify the role of oxygen gas in the ETC identify the components that oxidize NADH versus FADH2 explain the difference between cytoplasmic NADH versus mitochondrial NADH explain the creation of the electrochemical gradient and the production of ATP from chemiosmosis account for the number of ATP produced in oxidative phosphorylation
