Oxygen is one of the most electronegative elements in the biological world. This electronegativity is needed on the end of the electron transport chain. Electrons are passed from one complex or cytochrome to the next, and each successive molecule to be reduced needs to have a greater attraction for electrons than the last. So the end molecule, oxygen, needs to be electronegative enough to pull those electrons away, split and bond with two hydrogens to form water.
What else can I help you with?
What raw material is needed in the second part of cellular respiration that is not needed in the first part of the process?
In the second part of cellular respiration, specifically during the Krebs cycle and oxidative phosphorylation, oxygen is the key raw material needed that is not required in the first part, glycolysis. Glycolysis occurs in the cytoplasm and does not need oxygen, while the Krebs cycle and oxidative phosphorylation take place in the mitochondria and rely on oxygen to efficiently produce ATP. This oxygen is essential for the final electron acceptor in the electron transport chain, facilitating the production of water and enabling the generation of a significant amount of ATP.
Another name for electron transport chain is?
The electron transport chain is also known as the respiratory chain.
Is oxidative phosphorylation necessary for metabolism function?
Yes, oxidative phosphorylation is a vital part of cellular metabolism as it produces the majority of ATP in aerobic organisms. ATP is the primary energy source for cellular processes, making oxidative phosphorylation crucial for overall metabolism function.
Where does oxidative phosphorylation take place in a eukaryote?
Mitochondria
In order for cells to produce the MOST energy what gas should be present?
Oxygen to accept the electrons from the electron transport chain during oxidative phosphorylation.
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 the opposite of oxidative phosphorylation?
The opposite of oxidative phosphorylation is not a specific biological process, as it refers to the metabolic pathway that occurs in mitochondria to generate ATP from ADP using oxygen. However, an anaerobic process like fermentation can be considered as an alternative to oxidative phosphorylation.
What portion of aerobic respiration requires oxygen?
glycolysis, Krebs cycle, oxidative phosphorylation
What are the key differences between aerobic glycolysis and oxidative phosphorylation in terms of energy production in cells?
Aerobic glycolysis produces energy quickly but in small amounts, while oxidative phosphorylation produces energy more slowly but in larger amounts. Aerobic glycolysis occurs in the cytoplasm and does not require oxygen, while oxidative phosphorylation occurs in the mitochondria and requires oxygen.
What organnelle needs oxygen to make energy?
The mitochondria generates ATP by means of oxidative phosphorylation.
What is the final electron acceptor of the electron transport chain that functions in aerobic oxidative phosphorylation?
oxygen
The final electron acceptor of the electron transport chain that functions in oxidative phosphorylation is?
Oxygen is the final electron acceptor of the electron transport chain in oxidative phosphorylation. It accepts electrons from complex IV (cytochrome c oxidase) and combines with hydrogen ions to form water.
Compare and contrast photophosphorylation and oxidative phosphorylation?
Oxidative phosphorylation is ATP synthesis driven by electron transfer to oxygen and photophosphorylation is ATP synthesis driven by light. Oxidative phosphorylation is the culmination of energy-yielding metabolism in aerobic organisms and photophosphorylation is the means by which photosynthetic organisms capture the energy of sunlight, the ultimate source of energy in the biosphere.
Where is oxygen needed in a cell?
Oxygen is needed in the mitochondria of a cell for aerobic respiration, the process that produces ATP (energy) for the cell. Oxygen is the final electron acceptor in the electron transport chain, allowing for the production of ATP through oxidative phosphorylation.
What raw material is needed in the second part of cellular respiration that is not needed in the first part of the process?
In the second part of cellular respiration, specifically during the Krebs cycle and oxidative phosphorylation, oxygen is the key raw material needed that is not required in the first part, glycolysis. Glycolysis occurs in the cytoplasm and does not need oxygen, while the Krebs cycle and oxidative phosphorylation take place in the mitochondria and rely on oxygen to efficiently produce ATP. This oxygen is essential for the final electron acceptor in the electron transport chain, facilitating the production of water and enabling the generation of a significant amount of ATP.
Which cells use oxidative phosphorylization?
Cells with mitochondria carry out oxidative phosphorylation. Oxidative phosphorylation involves the transfer of electrons in mitochondrial protein complexes that serve as electron donors and electron acceptors. The process yields molecular oxygen and energy in form of adenosine triphosphate.
Occurs in the mitochondria which organisms take nutrients and oxygen to produce energy?
This process is called oxidative phosphorylation OR cellular respiration
