To convert oxygen in the air into a usable form in the blood stream. Without adequate oxygen in the blood your tissues will not get enough oxygen to function properly resulting in tissue ischemia (suffocating) and necrosis (death)
No it does not as it can also respire anaerobicallyOxygen is needed for aerobic respiration only.Anaerobic respiration does not need
Cellular respiration need oxygen. This oxygen is supplied by external respiration
For cellular respiration you need oxygen.
Oxygen is the gas that is required for respiration.
Sugars are the fuel for respiration. Respiration fulfills the energy need of cell
Nothing! as we are aerobes and need oxygen for respiration.
a person needs oxygen and glucose for respiration
They are for aerobic respiration. It produces energy in cells
For respiration you need oxygen and glucose.
Cellular respiration can be aerobic and anaerobic. Aerobic respiration requires oxygen, anaerobic respiration does not need oxygen.
When oxygen runs out, the muscles and other cells need to obtain energy from oxygen and nutrients. Anaerobic respiration (respiration without oxygen) fills this need.
Respiration is Oxygen in and Carbon Dioxide out. People need to respire to live.
