What molecules carry high-energy electrons into the electron transport chain?
NADH and FADH2 are the molecules that carry high-energy electrons into the electron transport chain. These molecules are produced during glycolysis and the citric acid cycle and donate their electrons to the chain to generate ATP through oxidative phosphorylation.
What causes the electrons to become excited and move into the electron transport chain?
Electrons become excited in the electron transport chain due to the energy input from electron carrier molecules like NADH and FADH2. These electron carriers donate the electrons to the proteins in the chain, creating a flow of electrons that drives the production of ATP.
What products of the citric acid cycle are needed for the electron transport chain?
NADH and FADH2 are the main products of the citric acid cycle that are needed for the electron transport chain. These molecules carry high-energy electrons to the electron transport chain, where they donate the electrons to generate ATP through oxidative phosphorylation.
What do glycolysis and the electron transport chain have in common?
Both glycolysis and the electron transport chain are essential processes in cellular respiration. Glycolysis breaks down glucose into pyruvate in the cytoplasm, while the electron transport chain produces ATP by transferring electrons through a series of proteins in the mitochondria. Both processes ultimately generate ATP, the energy currency of the cell.
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.
The energy of the electrons passing along the electron transport chain is used to make what?
ATP molecules
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.
What does the electron transport chain use the high-energy electrons from the KReb cycle for?
To make molecules of ATP.
What molecules carry high-energy electrons into the electron transport chain?
NADH and FADH2 are the molecules that carry high-energy electrons into the electron transport chain. These molecules are produced during glycolysis and the citric acid cycle and donate their electrons to the chain to generate ATP through oxidative phosphorylation.
What is the series of special molecules in the mitochondria that receive the high energy electrons from the carriers called?
The electron transport chain is a series of special molecules in the mitochondrion that receives the high-energy electrons from the carriers.
Does Electron Transport supply or store energy?
Electron transport in the mitochondria supplies energy by generating ATP through the transfer of electrons along the electron transport chain.
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
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.
What allows the passage of electrons along the series of carrier molecules from higher to a lower energy level?
The electron transport chain.
High energy electrons that move down the electron transport chain ultimately provide the energy needed to?
...convert ADP into ATP in the process known as oxidative phosphorylation.
Where do electrons get their energy in photosystem II?
From energy in photons
What causes the electrons to become excited and move into the electron transport chain?
Electrons become excited in the electron transport chain due to the energy input from electron carrier molecules like NADH and FADH2. These electron carriers donate the electrons to the proteins in the chain, creating a flow of electrons that drives the production of ATP.
