Explain why a lack of oxygen in our cells causes less energy to be available to do cellular work
What will be an ideal response?
The best responses will include a discussion of oxygen as the terminal electron acceptor in the electron transport chain. If oxygen does not accept those electrons, much of a cell's ATP will not be produced. With less ATP, less cellular work will be completed. Also, if oxygen is not present to accept the electrons and the hydrogen ions once they have passed down the electron transport chain, the entire process quickly stops. If the organism or cell can use anaerobic energy harvest/pathway, then only two ATPs will be produced for each glucose molecule.
