• Describe the electron transport chain - how it works and what it accomplishes - proton gradient forms and H+ pushes thru ATP synthase, creating ATP- formed from NADH and FADH2-electrons adopted by H20 (O2 is the last electron acceptor) • Explain what residual lung volume refers to and why it exists - Residual volume is the volume that is never exchanged. It is the amount of air left in the lungs after maximum exhalation. Residual volume exists because if not, our lungs would collapse....
