Answer 1

Explanation:

Oxygen, through a process called oxidation, chemically changes food and liquid into energy. It's this "oxygen fire" that contracts our muscles, repairs our cells, feeds our brains, and even calms our nerves. Not only that, but breathing is our body's chief cleansing tool.

Answer 2

Answer:

Oxygen is important to every cell in your body. Without it, your cells can’t make energy, and their metabolism is less effective. You switch from a highly efficient energy-making machine to being 16 times less efficient and generating a lot of lactic acid (which is what builds up in your muscles and makes you sore). Without sufficient oxygen, we perform less efficiently.
