What else can I help you with?
When electrons are transferred through a series of steps that release energy it is?
known as an electron transport chain. This process occurs in cellular respiration and photosynthesis where electrons move through protein complexes, releasing energy that is used to create ATP.
Where do NADH and FADH go to harvest their energy?
NADH and FADH are molecules that carry high-energy electrons to the electron transport chain in the inner mitochondrial membrane. There, these electrons are used to generate ATP through a series of redox reactions.
How high energy electrons are used in electron transport?
The energy molecule formed by the electron transport chain is called adenosine triphosphate, or ATP. Anywhere from 34 to 36 ATP can be produced during the electron transport chain.
What is the passing of electrons along a series of molecules releasing energy as the go is known as a?
This process is known as electron transport chain. It is a series of protein complexes and molecules within the inner membrane of the mitochondria that transfer electrons and generate a proton gradient, ultimately producing ATP through oxidative phosphorylation.
Why do high-energy electrons need carrier molecules?
High-energy electrons are unstable and reactive, so they need carrier molecules to transport them safely without causing damage to the cell. Carrier molecules such as NADH and FADH2 can carry high-energy electrons during cellular respiration, allowing them to participate in energy-producing reactions without causing harm.
Where does the electron transport chain get high energy electrons that are passed down the chains?
High-energy electrons from NADH and FADH2 are passed along the electron transport chain
Does Electron Transport supply or store energy?
The purpose of the Krebs cycle is to produce ATP or create molecules that will create ATP in the electron transport chain (NADH and FADH2)
Series of electron acceptors in the thylakoid membrane that removes energy from excited electrons to produce ATP?
The series of electron acceptors in the thylakoid membrane is known as the electron transport chain. As electrons move through the chain, they lose energy, which is used to pump protons across the membrane, creating a proton gradient. This gradient is then used by ATP synthase to produce ATP through a process known as chemiosmosis.
What happens to electrons when pigments in photosystem II absorbs light?
they move through an electron transport chain to photosystem 1
What an electron transport chain?
in this step the energy carried by electrons is used to synthesize (ATP). In electron transport chain NADH and FADH2 realese electrons and hydrogen ions. These electrons are taken up by a series of electron carriers. When electrons move through the series of electron carriers they lose electrons and hydrogen ions combine with moleculaer oxygen to form water.
What does the electron transport chain use the high energy electrons for the Krebs cycle for?
The electrons are passed down the electron transport chain for use in ATP production.
Where does the electron transport chain get the high-energy electrons that are passed down the chain?
The high-energy electrons in the electron transport chain are derived from molecules like NADH and FADH2, which are generated during cellular respiration in processes like glycolysis and the citric acid cycle. These molecules donate their electrons to the chain, where they are passed down through a series of protein complexes to generate ATP.
Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?
The electron transport chain is a series of protein complexes embedded in the inner mitochondrial membrane. As electrons pass through this chain, energy is released and used to pump protons across the membrane, creating an electrochemical gradient. This gradient is then used by ATP synthase to generate ATP, the main energy source for cellular functions.
What Series of electron acceptors in the thylakoid membrane remove energy from excited electrons to produce ATP?
The series of electron acceptors in the thylakoid membrane that remove energy from excited electrons to produce ATP is known as the electron transport chain (ETC). As electrons move through the ETC, their energy is used to pump protons across the membrane, creating a proton gradient. This gradient drives ATP synthesis through ATP synthase.
Most energy that enters electron transport enters as?
Most energy that enters the electron transport chain comes from the oxidation of glucose during glycolysis and the citric acid cycle. This energy is then transferred to the electron carriers NADH and FADH2, which deliver the electrons to the electron transport chain to generate ATP through oxidative phosphorylation.
What is the energy of the high energy electrons used for every time high energy electrons move down the electron transport chain?
To transport H+ ions out of the matrix.
What is passed from protein to protein in the electron transport chain?
Energy is transferred to the chain of proteins in the electron transport. A electron transport chain is a series of compounds that transfer electrons from electron donors to electron acceptors through redox reactions.
