The last stage of cellular respiration is called the?
Electron Transport SystemThe electron transport chain
Why is oxygen needed to produce ATP on the cristae of mitochondrion?
Oxygen is needed to produce ATP on the cristae of the mitochondrion because it serves as the final electron acceptor in the electron transport chain. During cellular respiration, electrons are passed along the electron transport chain, generating a proton gradient across the inner mitochondrial membrane. Oxygen then combines with these electrons and protons to form water, allowing the electron transport chain to continue functioning and ultimately producing ATP through oxidative phosphorylation. Without oxygen, the electron transport chain would be unable to function properly, leading to a decrease in ATP production.
Explain what happens in the electron transport chain?
as electrons from the Krebs cycle move down the electron transport chain energy level is reduced.
Where does the electron transport chain take place during cellular respiration?
The electron transport chain takes place in the inner mitochondrial membrane during cellular respiration. It is the final stage of aerobic respiration where electrons are passed along a series of protein complexes to generate ATP.
What happens to the energy level as electrons are passed along in electron transport?
They begin to electrolyze, a term used for giving off static charge.
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.
What happens when electrons are passed the electron transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
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
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.
Series of molecules down which excited electrons are passed in a thyakoid membrane?
electron transport chain
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.
What happens to electrons when pigments in photosystem II absorbs light?
they move through an electron transport chain to photosystem 1
What is the series of molecules through which excited electrons are passed down a thyroid membrane called?
electron transport chain
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 are electrons passed from during electron transport chain?
Electrons are passed from one protein complex to another in the electron transport chain, which is a series of protein complexes embedded in the inner mitochondrial membrane. This process generates a proton gradient that drives the production of ATP, the cell's energy currency.
What happens after sunlight hits photo system two?
After sunlight hits Photosystem II, it energizes the electrons in the chlorophyll molecules. The energized electrons are then passed through an electron transport chain, generating ATP and NADPH molecules through the process of photophosphorylation.
