Is the electron transport chain also called oxidative phosphorylation?
The respiratory chain, otherwise known as the electron transport chain, resides in the mitochondria. The chain consists of a series of electron carriers which can accept and then donate electrons, while the resulting production of energy is used to stimulate the formation of ATP via oxidative phosphorylation.
How oxidative phosphorylation is different from substrate level phosphorylation describe the role of electron transport chain in energy production?
The main difference between substrate level phosphorylation and oxidative phosphorylation is that substrate level phosphorylation is a direct phosphorylation of ADP with a phosphate group by using the energy obtained from a coupled reaction whereas oxidative phosphorylation is the production of ATP from the oxidized …
What pathway is oxidative phosphorylation?
Oxidative phosphorylation is the metabolic pathway in which electrons are transferred from electron donors to electron acceptors in redox reactions; this series of reactions releases energy which is used to form ATP.
What is ETS and oxidative phosphorylation?
Step by step answer: The process of oxidative phosphorylation involves a flow of electrons through the electron transport chain, which is basically a series of proteins and electron carriers present within the mitochondrial membrane. …
What is oxidative phosphorylation also known as?
Oxidative phosphorylation is also known as the electron transport chain. It includes the reactions that result in the synthesis of ATP from ADP + Pi.
What is the difference between the electron transport reactions of mitochondria and the ones which take place in photosynthetic process?
One important difference between electron transport in chloroplasts and that in mitochondria is that the energy derived from sunlight during photosynthesis not only is converted to ATP but also is used to generate the NADPH required for subsequent conversion of CO2 to carbohydrates.
What is the major difference between substrate-level phosphorylation and oxidative phosphorylation?
Substrate level phosphorylation directly transfers a phosphate group from the substrate (phosphorylated compound) to ADP to produce ATP. Oxidative phosphorylation is a process by which energy released by chemical oxidation of nutrients is used for the synthesis of ATP.
How does oxidative phosphorylation differ from substrate-level phosphorylation quizlet?
Both processes produce ATP from ADP and Pi, but substrate level phosphorylation occurs when enzymes remove a “high-energy” phosphate from a substrate and directly transfer it to ADP, while oxidative phosphorylation is based on electrons moving through and ETC and production of a proton-motive force that drives ATP …
What type of phosphorylation occurs in electron transport chain?
oxidative phosphorylation
What is oxidative phosphorylation? Oxidative phosphorylation is the process where energy is harnessed through a series of protein complexes embedded in the inner-membrane of mitochondria (called the electron transport chain and ATP synthase) to create ATP.
What happens to electrons as they pass down the electron transport chain?
The electrons passing through the electron transport chain gradually lose energy, High-energy electrons donated to the chain by either NADH or FADH2 complete the chain, as low-energy electrons reduce oxygen molecules and form water. The end products of the electron transport chain are water and ATP.
What is the main difference between substrate level phosphorylation and oxidative phosphorylation?
The key difference between substrate level phosphorylation and oxidative phosphorylation is that in substrate level phosphorylation, a phosphate group from a phosphorylated compound is directly transferred to ADP or GDP to form ATP or GTP without involving another molecules while in oxidative phosphorylation, nutrients …
What are electron carriers in oxidative phosphorylation?
Oxidative phosphorylation is the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH 2 to O 2 by a series of electron carriers. This process, which takes place in mitochondria, is the major source of ATP in aerobic organisms (Figure 18.1).
What is the formula for electron transport chain?
The overall electron chain transport reaction is: 2 H + + 2 e + + 1/2 O 2 —> H 2 O + energy Notice that 2 hydrogen ions, 2 electrons, and an oxygen molecule react to form as a product water with energy released in an exothermic reaction. This relatively straight forward reaction actually requires eight or more steps.
What are the steps of oxidative phosphorylation?
Steps of Oxidative Phosphorylation Before the Electron Transport Chain. For the electron transport chain to be able to pump protons to one side of the mitochondrial inner membrane, it must first have a source Within the Electron Transport Chain. ATP Synthesis.
What are electrons passed from during electron transport chain?
The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy. Electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen. During the passage of electrons, protons are pumped out of the mitochondrial matrix across the inner membrane and into the intermembrane space.
What goes on in the electron transport chain?
The electron transport chain involves a series of redox reactions that relies on protein complexes to transfer electrons from a donor molecule to an acceptor molecule. As a result of these reactions, the proton gradient is produced, enabling mechanical work to be converted into chemical energy, allowing ATP synthesis.
