What is the product of the electron transport chain in mitochondria?
Mitochondrial electron transport chains. Most eukaryotic cells have mitochondria, which produce ATP from reactions of oxygen with products of the citric acid cycle, fatty acid metabolism, and amino acid metabolism.
What feeds the electron transport chain?
All of the electrons that enter the transport chain come from NADH and FADH 2start subscript, 2, end subscript molecules produced during earlier stages of cellular respiration: glycolysis, pyruvate oxidation, and the citric acid cycle.
Where does respiratory electron transport occur in mitochondria?
The ETC is a collection of proteins bound to the inner mitochondrial membrane and organic molecules, which electrons pass through in a series of redox reactions, and release energy.
What is the respiratory chain in mitochondria?
The mitochondrial respiratory chain (MRC) is comprised of ~92 nuclear and mitochondrial DNA-encoded protein subunits that are organized into five different multi-subunit respiratory complexes. These complexes produce 90% of the ATP required for cell sustenance.
What does the electron transport chain produce in cellular respiration?
The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria.
What are the reactants and products of the ETC?
Electron Transport Chain Reactants As electrons are transferred, protons are pumped across the membrane to create a proton gradient. During ATP synthesis, ADP is phosphorylated to produce ATP. Oxygen acts as the final electron acceptor, resulting in the formation of water.
Where is the respiratory electron transport system?
Inner mitochondrial membrane
Where is the respiratory electron transport system (ETS) located in plants? The correct answer is (4) Inner mitochondrial membrane. This is because – Electron transport system is located in inner mitochondrial membrane.
What are the two electron carriers within the mitochondrial respiratory chain?
The two components that carry electrons between the three major enzyme complexes of the respiratory chain—ubiquinone and cytochrome c—diffuse rapidly in the plane of the inner mitochondrial membrane.
Why electron transport chain is called respiratory chain?
The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism.
What are the products in the process of cellular respiration?
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What do you call the process wherein plants make their own food?
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
What are the reactants and products of the electron transport chain during cellular respiration?
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
