List, in order, the stages of aerobic cellular respiration.
What will be an ideal response?
Cellular respiration begins with glycolysis. The resulting pyruvates are modified and then moved into the citric acid cycle within the matrix of the mitochondria. Electron carriers such as NADH formed during these early stages of respiration are then moved to the electron transport chain in which they deliver electrons. The electrons are passed down the electron transport chain, producing ATP and ultimately combining with oxygen.
