• Check out this awesome video about the electron transport chain.

• The first part of cellular respiration involves breaking down sugar molecules in glycolysis and the citric acid cycle. Learn more about those processes in this video.

• After breaking up the sugar molecule, electrons that result from that breakup generate most of the ATP in the mitochondria. This next video on the electron transport chain and chemiosmosis explains how that happens.

• This last video is about how cells manage without oxygen.
