Where are the low-energy electrons located after the electron transport chain is completed?
Where are the low-energy electrons located after the electron transport chain is completed? They are located in the bonds of H2O.
How much energy does electron transport chain?
34 ATP molecules
Electron transport chain This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.
What part of the electron transport chain is most electronegative?
The electron carriers in the electron transport chain are organized in order of increasing electronegativity. Complex I is the least electronegative, and complex IV is the most electronegative.
Which of the following passes high energy electrons into the electron transport chain?
Answer and Explanation: High energy elections are passed into the electron transport chain by means of an electron carrier called NADH.
Why is oxygen important in the electron transport pathway and ATP synthesis?
Why is oxygen important in the electron transport pathway and ATP synthesis? Oxygen accepts electrons at the end of the electron transport chain to free the pathway for a new set of electrons.
Why does the cell convert the energy in the bonds of glucose to ATP?
Energy contained in the bonds of glucose is released in small bursts, and some of it is captured in the form of adenosine triphosphate (ATP), a small molecule that powers reactions in the cell. Much of the energy from glucose is dissipated as heat, but enough is captured to keep the metabolism of the cell running.
Does an electron transport chain go from high to low?
In prokaryotes, the electron transport chain components are found in the plasma membrane. As the electrons travel through the chain, they go from a higher to a lower energy level, moving from less electron-hungry to more electron-hungry molecules.
How many electrons must move down the electron transport chain before energy is made?
Every 2 high-energy electrons pass down the Electron Transport Chain, their energy is used to transport Hydrogen Ions across the membrane.
What carries high energy electrons?
High-energy electrons are released from NADH and FADH2, and they move along electron transport chains, like those used in photosynthesis. The electron transport chains are on the inner membrane of the mitochondrion. As the high-energy electrons are transported along the chains, some of their energy is captured.
What is the energy of the electrons passing along the electron transport chain used for?
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
