What else can I help you with?
How does the presence of a phenyl group affect the electron-withdrawing properties of a molecule?
The presence of a phenyl group in a molecule increases its electron-withdrawing properties. This is because the phenyl group contains a delocalized pi-electron system, which can withdraw electrons from the rest of the molecule, making it more electron-deficient.
The electrons of which element are the primary substance carried by the electron transport system?
The electrons of hydrogen (H) are the primary substance carried by the electron transport system. In the form of hydrogen atoms or ions, electrons are shuttled through the system to generate ATP in cellular respiration.
Where does a Electron Transport Chain happen?
In aerobic respiration, electron transport occurs inside the mitochondria. In photosynthesis, electron transport occurs inside the chloroplasts.
What happens when that final electron acceptor accepts electrons from the electron transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
Is the energy from sunlight trapped by chlorophyll located in the electron transport chain?
No, the energy trapped by chlorophyll is located in photosystem I and II. Light energy is first captured by PS II and an electron is then transferred to a primary electron acceptor known as plastoquinone. Pq then transfers it's electron to the cytochrome complex that transfers its energy to the electron transport system which passes it on to plastocyanin which in turn gives its electron to PS I where it is re-excited by photons. This process is known as the electron transport but the energy captured by chlorophyll is located in the photosystems.
Which of these molecules is not a product of the electron transport system a nad plus or b oxygen or c fad or d water?
The answer would be B) oxygen. In the electron transport chain, oxygen is a reactant. It reacts with 4 electrons and 4 hydrogens to form 2 water molecules. NAD plus is a product of NADH losing an electron. FAD is a product of FADH2 losing an electron. And water is a product of the preceding reaction that I gave.
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.
When and where does the electron transport take place?
The location of the electron transport system depends on the cell type.~The electron transport system is embedded in the inner membrane of the mitochondria for animal, plant and fungus cells.~The electron transport system is also in the thylakoid membrane of chloroplasts in plant cells.
Where in a eukaryotic cell does the Electron Transport System operate?
The electron transport system operates in the cristae of the mitochondrion in an eukaryotic cell.
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 occurs in the electron transport system?
Anacrobic respiration
How does the electron transport system function?
thylakoid membrane
What is required to start and what is produced by the hydrogen and electron transport system?
The proteins involved in the chain, complete with ATP synthase in the end for oxidative phosphorylation, some electron carriers like NADH and FADH2, and the final electron acceptors such as O2.
What is the energy made from the electron transport system used for?
electricity
When oxygen is not present?
there is no oxygen present in the electron transport system.
Is oxygen use in aerobic respiration?
electron transport system
When oxygen not present?
there is no oxygen present in the electron transport system.
