The cells in G0 phase do not go through mitosis whatsoever. These cells only do what they are initially suppose to do, and do not prepare for a division. Many cells in your body are like this. Brain cells are in G0 phase and do not EVER replace itself. However, many cells may also trigger its phase from G0 phase to G1 phase when more cells are needed. When a liver is critically damaged, the liver cells are triggered back to G1 phase to replenish its lost cells.
Cells cannot perform their functions. Cells need two things to function: fuel and oxygen. These allow all the cells in your body to produce energy to do any work that you want to do, like digesting or thinking. Without oxygen, your cells cannot undergo cellular respiration. It will fall back on anaerobic respiration, which produces less energy and has a by-product of lactate (Iactic acid). Failing that, your cells will begin to shut down.
