Oxygen is the final electron acceptor. Oxygen, with it's great electronegativity, pulls electrons through the electron transport chain where these electrons provide the motive force to pump protons into the outer lumen of the mitochondria. When these protons fall down their concentration gradient oxygen is there to pick then up with the electrons and form water.

Oxygen is needed for the final step of cellular respiration, which is the electron transport chain, because it is the final electron acceptor. Without oxygen, the electron transport chain cannot function properly, leading to a halt in the production of ATP through oxidative phosphorylation.

What is needed for cellular respiration to occur in cells reactants?

Cellular respiration requires oxygen and glucose as reactants to occur in cells. Oxygen is needed as the final electron acceptor in the electron transport chain, while glucose is broken down in a series of metabolic pathways to produce ATP, the cell's energy currency.


What substances does the body need to carry out cellular respiration?

The body needs glucose and oxygen to carry out cellular respiration. Glucose is the primary source of energy, and oxygen is needed as the final electron acceptor in the electron transport chain to produce ATP.


What are the materials needed in cellular respiration?

The materials needed in cellular respiration are glucose and oxygen. Glucose is the source of energy, and oxygen is the final electron acceptor in the electron transport chain, which drives the production of ATP in the mitochondria.


Is glucose and oxygen needed during the respiration system?

Yes, glucose and oxygen are needed in the respiratory system for the process of cellular respiration. Glucose is used to create energy through the process of glycolysis and the citric acid cycle, while oxygen is necessary for the final stage of cellular respiration, which is the electron transport chain where ATP is produced.


What gas is used by eukaryotic cells for cellular respiration?
