Need oxygen to survive

Answer 1

All living cells require oxygen to metabolize (eat) glucose (sugar) in order to generate the energy the cells require to live. Inside the cell, a chemical reaction oxidizes glucose (combines glucose with oxygen) to produce water, carbon dioxide, and adenosine triphosphate (ATP). It is the ATP itself that provides the energy in the form the cell needs to carry out the functions that sustain its life.

Without oxygen, the call cannot create ATP, and without ATP, the cell starves and dies. When too many critical cells (heart, lung) die from oxygen starvation, then you die too.

Answer 2

Yes you do because its without oxygen you will die




You do not NEED oxygen to breathe. You NEED to breathe oxygen.


It's different. Let me explain.


Breathing is the inhaling and exhaling air. When we inhale, we inhale oxygen and other chemicals. If we INHALE oxygen that means it wasn't present before yet, we BREATHED. Please phrase question.


Oxygen is needed because it contributes to the respiration process. Respiration is the process by which energy from food is converted to energy. The chemicals involved in this process:


Glucose + Oxygen = Carbon Dioxide + Water + Energy


Hence, why you need oxygen.

Answer 3

Same reason we need food for fuel - without it, we'd die.

Just the way we are...

But another way you could look at it is that if there were no oxygen, like in space, our heads would blow up.

Answer 4

It is a involuntary action controlled by our lungs

Answer 5

Yes, we breathe in Oxygen so it is definitely need to survive.
