What is oxygen needed for in the amoeba?

The amoebae is an eukaryote, so it uses oxygen for the same reason you do. Oxygen is the final electron acceptor in the process of oxidative phosphorylation that takes place in the mitochondria.


Glycolysis and oxidative respiration are different in that?

Glycolysis occurs in the absence of oxygen while oxidative respiration requires oxygen


What are oxidative enzymes?

Oxidative enzymes are enzymes that catalyze oxidation reactions. This means that a negatively charged electron is grabbed from certain compounds and then supply oxygen.


Why is oxygen needed for?

Oxygen is used as an electron carrier in oxidative phosphorylation during aerobic respiration. If there's a lack of oxygen the body starts to respire anaerobically, which is nowhere near sufficient for the body's needs


What is an electron acceptor in oxidative phosporylation?

Oxygen


Fermentation would occur?

When there is not enough oxygen for oxidative respiration.


Why is oxidative respiration unable to occur without oxygen?

Oxygen is needed as the final electron acceptor for the electron transport chain on the inner mitochondrial membrane. Note: Some organisms use other molecules in this role however oxygen is the most effective.


The final electron acceptor of the electron transport chain that functions in oxidative phosphorylation is?

Oxygen is the final exceptor


What is oxidative metabolism?

Oxidative metabolism, in the words of my Biology professor, is the use of oxygen, release of carbon dioxide, and most ATP formation in the metabolic pathway.


Is oxidative respiration an aerobic process?

True, aerobic means that it needs oxygen. Oxidative respiration is cellular respiration with oxygen as the final acceptor at the end of the cycle.
