Hi, the given question from chemo -osmotic hypothesis.
00:07
So that, so during the chemo -osmosis, electron carrier like nadh and also fadh, it donates the electron to the electron transport chain.
00:57
The election's confirmation change, this electron, causes conformational changes in the shape of the protein to pump hydrogen ion across a selective permeable cell membrane.
01:41
The uneven distribution of hydrogen ion across the cell membrane establishes both the concentration and electron gradient so that thus a electrochemical gradient, it is called electrochemical gradient, so that only to the hydrogen ions positive charge and their aggregation on the one side of the membrane.
02:44
So that if the membrane were opened to diffusion by the hydrogen ion, ion would tend to spontaneously diffuse back across to the matrix driven by their electrochemical gradient.
03:01
However, many ions cannot diffuse through the non -polar reason of the phospholipid membrane without the aim of ion channels.
03:13
Similarly, hydrogen ions in the matrix space can only pass through the intermitocondrial membrane.
03:43
Through this membrane protein called synthesis.
03:54
We can say that atp synthesis so that this protein act as tini generator, protein act as tini generator turned by the force of the hydrogen ion diffusing through it down their electron chemical gradient the turning of this molecular machine harness the potential energy stored in the hydrogen ion gradient to add a phosphate to adp, addition of the phosphate to the adp to for adp, adnosine triphosphate.
05:04
So that chemo -osmosis is used to generate approximately 90 % of the atp during aerobic glucose metabolism...
