Chapter 14, Problem 6RQ
Summary Introduction
To review:
The role of substrate dehydrogenase, the quinones, and the cytochrome oxidase in the respiratory ETS.
Introduction:
The respiratory electron transport system (ETS) receives electrons from the NADH (nicotinamide adenine dinucleotide hydrogen) as well as FADH2 (flavin adenine dinucleotide dihyrogen) and helps in transferring electrons to oxygen for the production of water. In aerobic respiration, the electron transport chain is the last component. It is part of the glucose
