Why do cells require oxygen​

Answer 1

Answer:

Every cell in your body needs oxygen to function. ... Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar.If blood stops flowing, oxygen can't get delivered to your cells. ... Organisms such as humans require oxygen to produce as much energy as they need to function. Without aerobic metabolism, cells cannot maintain their compostion and so tend to equilibrate with environment, that is, die.
