What is oxygen needed by most organisms in the process?
Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.
What process in animal cells requires oxygen?
Well, respiration usually requires oxygen, and animals get their oxygen by breathing. All vertebrate animals that live on land have lungs. When we breathe in, the muscle below the rib cage (called the diaphragm) is pulled down, and air gets sucked into the rib cage, filling the lungs.
What are the importance of oxygen to animals?
Oxygen is essential for respiration because the body uses it to 'burn' food molecules. Animals take in oxygen when inhaling and give off carbon dioxide when exhaling. Oxygen makes up almost 21% of the total gases in air, with most of the remaining gas being physiologically inert nitrogen.

Where does aerobic respiration occur?
Aerobic respiration consists of three stages: glycolysis, which occurs in the cytoplasm; and the Krebs cycle and electron transport chain, which occur in the mitochondria. The majority of the ATP is produced during the electron transport chain.
How many ATP molecules are produced in anaerobic respiration?
Aerobic cellular respiration can produce 36 to 38 molecules of ATP from one glucose molecule, whereas anaerobic respiration (glycolysis followed by fermentation) produces a net gain of only 2 molecules of ATP from one glucose molecule.
What is the process of cellular respiration that breaks down glucose molecules?
Animals and all life that requires oxygen to survive, use glucose and oxygen in aerobic cellular respiration. Aerobic cellular respiration breaks down glucose molecules, storing the energy released during the process in molecules of ATP (adenosine triphosphate), which provide the energy needed for cell (s) to do work.
What is the last electron acceptor in the electron transport chain?
Oxygen is the last electron acceptor in the electron transport chain, and combines with electrons and H+ ions, to form water, which is removed. A new oxygen molecule takes the place of the one that combined with hydrogen ions and electrons to form water, and the electron transport chain continues. Without oxygen , the hydrogen ions and electrons will have nowhere to go, the electron transport chain will back up, aerobic respiration will stop, most of the ATP will not be produced, resulting in death for organisms that cannot switch to anaerobic respiration to a sufficient degree to sustain life.
