Question

What do cells need oxygen for ​

Answer 1

Hello Queen Messy here!

Glycolysis in Respiration

Cells use oxygen to assist in cellular respiration. This type of respiration, called aerobic cellular respiration, converts stored energy into a usable form, chiefly by reacting glucose and oxygen through an intermediate. The first stage of aerobic cellular respiration, glycolysis, can be performed without oxygen. However, if oxygen is not present, cellular respiration cannot continue past this stage.

In glycolysis, glucose is converted to a carbon-based molecule called pyruvate. Two molecules of adenosinse tri-phosphate (ATP), a nucleotide that provides energy to cells, are generated during this process.

Answer 2

to break chemical bonds

Step-by-step explanation:

The blood transports the sugars to the cells, where the mitochondria break up their chemical bonds to release the energy they contain. Cells need oxygen to be able to carry out that process. As every cell in our body needs energy, every one of them needs oxygen. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released.
