Hello students, the electron transport chain is a series of proteins and organic molecules which are found in the inner membrane of the mitochondria.
00:09
Electrons are passed from one member of the transport chain to another in a series of redox reaction.
00:15
Energy is released in this reaction is captured as a proton gradient which is then used to make atp as you can see here in this diagram and the process of making this atp is called chemoosmosis.
00:28
Together the electron transport chain and this chemoosmosis make up oxidative phosphorylation.
00:36
In electron transport chain the first step is the delivery of electrons by nadh and fadh2.
00:44
Reduced electrons carrier these two are the electron reduced carrier.
00:49
From other step of cellular respiration transfer their electrons to molecules near the beginning of the electron chain.
00:55
In the process they turn back into nad plus and fad which can be reused in other steps of cellular respiration.
01:03
Further electrons are transferred and when the electrons are transferred the protons are pumped into this intermembrane space.
01:11
Then there is splitting of oxygen to form water and then the gradient driven synthesis of atp.
01:20
Here what happen is as protons ion flow back down in their gradient and back into the matrix they pass through this enzyme called atp synthesis which harness the flow of protons and synthesize atp...
