When an individual stops breathing, brain cells die very quickly, but the cells in the heart are able to survive for longer. Which conclusion is best supported by these facts?

Brain cells are more specialized than muscle cells and require more oxygen.
Unlike heart cells, brain cells do not use ATP as their energy-storing molecule.
Unlike brain cells, heart cells can produce small amounts of ATP by going through fermentation.
Blood does not travel to the brain unless it first goes to the heart.
