Explain what happens in the electron transport chain?
as electrons from the Krebs cycle move down the electron transport chain energy level is reduced.
Why is oxygen needed to produce ATP on the cristae of mitochondrion?
1)ATP formed as electrons pass along transport chain 2)oxygen is terminal electron acceptor / accepts electrons from electron transport chain 3)electrons cannot be passed along electron transport chain if no O2 to accept them 4)forms H2O / accepts H+ from reduced NAD/FAD / oxidises reduced NAD/FAD
What happens in photopigments when they absorb photon energy?
Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
Why photosynthesizing plants rely on water?
Water plays a huge role in photosynthesis. It releases H+ ions that are used to generate energy that is in the form of ATP.
What is the role of photosystem 1 in the light reactions?
is a cluster of pigments, with a perticular chlorophyl in the center. The energy is absorbed and is then passed to the Hugh energy electrons, NADP will then pick up the electrons and make NADPH
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
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.
High-energy electrons from NADH and FADH2 are passed into and along the?
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?
Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?
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.
Where does the electron transport chain get the high-energy electrons that are passed down the chain?
The high-energy electrons that are passed to the electron transport chain combine with O2 and H+ ions. This results to the formation of water molecules.
What happens when electrons are passed the electron transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
Series of molecules down which excited electrons are passed in a thyakoid membrane?
electron transport chain
Which is the series of molecules through which excited electrons are passed down a thylakoid membrane?
electron transport chains
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 are electrons passed from during electron transport chain?
It is usually coming from the Krebs Cycle, also known as the Citric Acid Cycle.
What is the series of molecules through which excited electrons are passed down a thyroid membrane called?
electron transport chain
