Question

what is the role of oxygen during respiration

Answer 1

Oxygen is required during respiration as it helps in breaking the food into simpler substances which are then utilised by the body in development

Answer 2

Cellular respiration is the process cells use to make energy. Our body cells need oxygen to do this process, although other organisms, like yeast or bacteria, don't always need it. They have other ways of making energy. But since the focus of this particular lesson is on the role of oxygen, we'll stick with animal cells, like the ones in our body.

All body cells engage in cellular respiration. They use oxygen and glucose, a sugar found in the foods we eat and convert them to ATP (adenosine triphosphate), or cellular energy, and carbon dioxide. Although this process can be represented by a single equation, there are actually many small steps that take place before we actually use oxygen to get ATP
