Where do electrons get there energy in photosystem 2?
Excited electrons are transferred to an electron transport chain.
What atom accepts electrons at the of the electron transport chain?
The atom that accepts electrons at the end of the electron transport chain is oxygen. Oxygen acts as the final electron acceptor in aerobic respiration, combining with electrons and protons to form water.
The final acceptor of electrons in the electron transport chain is?
oxygen
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 is the function of oxegyn in the electron chain transport?
Oxygen functions as the final electron acceptor in the electron transport chain. It combines with electrons and protons to form water, allowing the transfer of electrons to produce ATP. This process is essential for cellular respiration and generating energy for the cell.
What acts as the hydrogen acceptor in the electron transport chain?
Oxygen acts as the final hydrogen acceptor in the electron transport chain. It receives electrons and protons at the end of the chain, combining them to form water.
How many protons are pushed through the membrane for NAD and FAD and why are they different amounts?
NAD+ typically contributes to the transport of three protons (H+) across the mitochondrial membrane during oxidative phosphorylation, while FADH2 contributes to the transport of two protons. The difference in the number of protons is due to where each electron carrier enters the electron transport chain; NADH donates electrons at Complex I, which pumps more protons, whereas FADH2 donates electrons at Complex II, which does not pump protons, leading to the lower proton count.
Which ion ends up in the intermembrane space during electron transport chain?
Protons (H+ ions) end up in the intermembrane space during the electron transport chain. These protons are pumped across the inner mitochondrial membrane from the matrix to the intermembrane space as electrons flow through the electron transport chain.
How many protons in total are pumped into the intermembrane space of a mitochondria through the electron transport chain, if each complex individually receives 2 electrons?
12 protons
What electron has 51 protons and 72 electrons?
This electron would have 51 protons and 51 electrons. The number of electrons in an atom is equal to the number of protons, as atoms are electrically neutral.
Which accumulates in the inter membrane space of the mitochondrion during electron transport?
During electron transport in the mitochondrion, protons (H+) accumulate in the intermembrane space. This happens as electrons are transferred through the electron transport chain, creating a proton gradient across the inner mitochondrial membrane. This gradient of protons is later utilized by ATP synthase to generate ATP through oxidative phosphorylation.
Why is oxygen needed for the final step in cellular respiration?
Oxygen is the final electron acceptor. Oxygen, with it's great electronegativity, pulls electrons through the electron transport chain where these electrons provide the motive force to pump protons into the outer lumen of the mitochondria. When these protons fall down their concentration gradient oxygen is there to pick then up with the electrons and form water.
