What else can I help you with?
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 form do proteins need to be in to go through the electron transport chain?
Proteins need to be in the form of enzymes embedded in the inner mitochondrial membrane to participate in the electron transport chain. These enzymes facilitate the transfer of electrons from one molecule to another, generating a proton gradient used to produce ATP.
An example of an electron carrier molecule?
One example of an electron carrier molecule is NAD+ (nicotinamide adenine dinucleotide). NAD+ is involved in redox reactions, acting as a carrier of electrons during cellular respiration to help generate ATP. It accepts electrons from substrates and becomes reduced to NADH, which can then donate the electrons to the electron transport chain for ATP production.
The electrons stripped from glucose in cellular respiration end up in which Compound?
The electrons stripped from glucose in cellular respiration end up in the molecule NADH (Nicotinamide adenine dinucleotide). NADH then carries these electrons to the electron transport chain to generate ATP through oxidative phosphorylation.
What is an example of an electron acceptor molecule?
An example of an electron acceptor molecule is oxygen (O₂). In cellular respiration, oxygen accepts electrons at the end of the electron transport chain, allowing for the production of ATP. Other examples include NAD⁺ and FAD, which also function as electron acceptors during metabolic processes.
How many electrons can a NADH molecule carry?
The electron transport chain is also known as the respiratory chain. NADH carries electrons in the form of hydrogen atoms to the electron transport chain.
Are excited electrons from the acceptor molecule sent to the electron transport chain?
Yes, excited electrons from the acceptor molecule are sent to the electron transport chain. This process allows the electrons to move through a series of protein complexes in the inner mitochondrial membrane, ultimately leading to the generation of ATP through oxidative phosphorylation.
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 molecule lose electrons in cell respiration?
In the third stage of cellular respiration (Electron Transport Chain), electrons are lost from the NADH and FADH2 molecules. These electrons travel down the electron transport chain which is in the inner membrane of the mitochondria and result in being reactants for the formation of H2O.
Is FADH2 an electron acceptor?
No, FADH2 is in the "accepted" state. FADH+ is the form of the molecule that is able to accept electrons.
Starting molecule of electron transport chain?
The starting molecule of the electron transport chain is NADH or FADH2, which are generated during glycolysis and the citric acid cycle. These molecules donate high-energy electrons to the electron transport chain, which then pass through a series of protein complexes to generate ATP through oxidative phosphorylation.
What molecule does oxygen became a part of at the and of the electron transport chain?
The oxygen combines with two hydrogens and the requisite electrons to become water.
Which molecule could be termed the final resting place last molecule to be reduced final electron acceptor of the electrons donated by nadh and fadh2 to the etc?
Oxygen is typically considered the final electron acceptor in the electron transport chain (ETC) during cellular respiration. It accepts electrons from NADH and FADH2 to form water, which marks the end of the electron transport chain and generates ATP through oxidative phosphorylation.
What part of a glucose molecule provides electrons in cellular respiration?
The hydrogen atoms attached to the carbon atoms in the glucose molecule provide electrons during cellular respiration. These electrons are transferred to the electron transport chain to produce ATP.
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 form do proteins need to be in to go through the electron transport chain?
Proteins need to be in the form of enzymes embedded in the inner mitochondrial membrane to participate in the electron transport chain. These enzymes facilitate the transfer of electrons from one molecule to another, generating a proton gradient used to produce ATP.
What molecule precedes the electron transport chain of both photo-system you and photo- system II?
The molecule that precedes the electron transport chain in both photosystem I and photosystem II is plastoquinone. Plastoquinone accepts electrons from the reaction center chlorophyll in both photosystems and transfers them to the cytochrome b6f complex to ultimately generate ATP.
