Ultimately to be the final electron acceptor of the electron transport chain. By it's great electrovegativity oxygen pulls electrons down the chain and electrons pump hydrogen ions into the outer lumen of the mitochondria. Then these hydrogen ions come down their concentration gradient through the ATP synthase and synthesize ATP. Oxygen picks the hydrogen ions up with electrons and forms water. So, oxygen is essential to oxidative phosphorilation and human respiration.

∙ 14y agoThe carbohydrates we eat turn into sugar. Your body stores this sugar in your liver until your body is ready to use it. Your pancreas releases insulin to tell your liver, "Release sugar." Then the sugar is carried to a cell. The cell places it in some mitochondria. It gets Oxygen from a red corpuscle. It takes the oxygen to the mitochondria. There it combines the Oxygen and the sugar and materials from the cell to create ATP or Adenosine triphosphate. ATP provides the power to run the cell. It acts like the gasoline in your car. Without gas your car won't go. If your body stops producing ATP, your cells don't go. You can use up all the carbohydrate stored in your liver and most of the fat stored in your body making ATP. Nothing can substitute for Oxygen.

Do plants cells need to carry out respiration?
yes because plants themselves respire carbon dioxide and realse oxygen.
Why does a plant cell have a cell wall and chlorophyll and an animal cell doesn't?
Its because the plant needs to be stable because it would be really floppy, and the animal cell does not because it can move around the animal and it does not need to be stablised. Animal cells do not have chlorophyll because they don't need it. Plant cells need them because they take in sunlight and turn it into a sugar that is used for food for energy. Animal cells do not get their energy from the sun directly, they get it from oxygen. Animal cells do not photosythesise, which is what chlorophyll is for.
Do animal cells use carbon dioxide?
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
Do animal cells respire?
Animal cells respire in order to refresh the blood cells with oxygen rich molecules. The oxygen is then transported to the rest of the body for muscle use.
Why do blood cells need oxygen?
Blood cells need oxygen to move and reproduce, without it, they would die. And in time, you would also die.
What gas do all plants and animal cells need?
Oxygen
Why do animal cells need oxygen most directly?
Produce ATP
What are the three thing plant cells and animal cells need?
Water, Oxygen and organic food for energy
Do white blood cells need oxygen?
yes, white blood cell have mitochondrion. Cellular respiration occurs in the mitochondrion.
Do plants cells need to carry out respiration?
yes because plants themselves respire carbon dioxide and realse oxygen.

Why do animal cells need plant cells?
animal cells can't make their own food, plant cells can so animal cells need to eat plant cells
What does blood carry to the cells of an animal?
In its most basic function, red blood cells act as oxygen-transports for animal cells.
Does animal cells have metabolism with or without oxygen?
yes they have to have oxygen in order to breathe
What waste do cells need to transport out of the cell?
Metabolic toxins, waster products like oxygen for plant cells and carbon dioxide for animal cells. Anything that is in excess
Do animal cells use carbon dioxide?
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
What gas do muscle cells need?
All cells need Oxygen.
