Question

Why do you think the body's cells need oxygen?

Answer 1

Answer: Majority of living things need oxygen to survive.

Explanation: If our cells in our body's don't get oxygen, cells will die. Though not all cells do not require oxygen in order to produce energy, the cells in the body requires oxygen for respiration in order to produce energy. Organisms need oxygen in order to grow. Without oxygen, our cells wouldn't be able to break down food that we need to survive. Our bodies' cells need oxygen for the structured use of glucose in cellular respiration.

Answer 2

The body's cells need oxygen to perform cellular respiration, which is the process of generating energy (ATP) from glucose and other nutrients. Oxygen is a critical component in the final step of cellular respiration called the electron transport chain, where it acts as the final electron acceptor.
