Why is oxygen needed for the final step in cellular respiration?
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.
Because cellular respiration requires oxygen it is said to be?
If oxygen is available, the process is an aerobic respiration, in opposite to anaerobic respiration, which does not need oxygen. More info can be found on http://en.wikipedia.org.wiki/Cellular_respiration
What is the purpose of light reactions?
it includes the passage of electrons along electron transport chain and produces NADPH and oxygen, and the synthesis of ATP. it includes the passage of electrons along electron transport chain and produces NADPH and oxygen, and the synthesis of ATP.
What is the difference between substrate level phosphorylation and chemiosmosis?
substrate level phosphorylation does not involve (electron transport chain), oxidative phosphorylation does. Substrate level phosphorylation involves the direct transfer of phosphate from a phosphate bearing molecule to ADP, thus yielding ATP. In cellular respiration, oxidative phosphorylation requires a protein, ATP synthase, to channel energy provided by a concentration of H ions; this energy results in the combining of phosphate with ADP.
Explain what happens in the electron transport chain?
as electrons from the Krebs cycle move down the electron transport chain energy level is reduced.

Why should you use oxygen?
oxygen is needed for all catabolic process for the production of energy it is need for the transport of energy in the form of electrons mainly in ELECTRON TRANSPORT CHAIN in mitochondria oxygen there act as last e acceptor
Why does your body need a continuous supply for oxygen?
Your body needs a continuous supply of oxygen due to the biochemical process of aerobic cellular respiration. During the last stage, called the electron transport chain, electrons are transferred along a series of chemicals called electron acceptors. As this occurs, energy is given off to produce molecules of ATP, the energy storage molecule of living things. Oxygen is the last electron acceptor, and once it gains the electrons it bonds with hydrogen to form water, removing the oxygen from the electron transport chain. If a new oxygen atom does not take its place immediately, the electron transport chain shuts down, and your cells will not be able to produce enough ATP to fuel their cellular processes, and they will die, and so will you. So you need a constant supply of oxygen in order to keep the electron transport chain working and producing enough energy (stored in ATP) for survival.
What is the first part of aerobic cellular respiration?
The Kreb's Citric Acid Cycle depends upon Oxygen for It's Proper Functioning. Remove Oxygen and the Respiratory System Reverts to the [anaerobic] Lactate Utilzation Back-up System.
What process is cellular respiration?
Cellular respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP. It occurs in the mitochondria of the cell and involves three main stages: glycolysis, the citric acid cycle, and oxidative phosphorylation. Oxygen is consumed during cellular respiration, and carbon dioxide and water are produced as byproducts.
What form do proteins need to be in to go through the electron transport chain?
Stripped of their electrons by electron carriers. Electrons are the only thing going through the electron transport chain, where their motive force is moving protons across membranes.
Where is the electron transport chain is located?
Inner membrane of the mitochondria

Why do organisms need a final electron acceptor?
A final electron acceptor that is a stronger oxidizing agent than the last oxidizing agent in the electron transport chain is needed to remove low-energy electrons from the chain so that new high energy electrons can enter the chain to generate more ATPs. Without a final electron acceptor the electron transport chain will be backed up with low energy electrons and eventually no ATP can be generated since no new electron can enter the chain.
Where in the cell do electron transport chain occur?
In the mitochondria. The complexes need for the electron transport chain are attached on the inner side of the inner mitochondrial membrane, which channels opening into the intermembrane space for pumping out protons.
Does respiration use oxygen?
Yes, respiration is the process by which cells break down glucose to release energy. In aerobic respiration, oxygen is used as the final electron acceptor in the electron transport chain to produce ATP, the cell's main energy source. Oxygen is necessary for this process to efficiently generate energy.
