It has considered the first question light reaction which occurs during photosynthesis in the gran of the plotoplast.
00:19
In this reaction a .d.
00:24
And madphr synthesized.
00:30
So from the light source that is from sunlight, light is captured by the reaction center consisting of p680.
00:46
That is prescientive photosystem 2.
00:49
Then the electron is released.
01:04
The electrons that are released are fio fighting transfer the electrons to the plastroquinone.
01:24
From plasterquinine electrons are transferred to plastocyanine and this is mediated by cytochrome b.
01:45
This whole process is known as oxidative phosphorylation.
01:50
In photosystem 1 we have reaction center p700 light strikes this photo system to p700 reaction center the electrons they are passed on to the feridoxy which acts an electron acceptor these electrons are transferred to nadp to form nadph with the help of nadph reductives in this process molecule oxen is liberated as a byproduct by photolysis of water.
02:58
So this was related to the light reaction that occurs in the gran of the chloroplast.
03:07
That is h2ocuse to h2 plus half o2.
03:14
This is water photolysis which occurs in presence of light.
03:24
Moving to the second question here.
03:30
Electron transport chain.
03:32
And oxidative phosphorylation.
03:37
These two are connected, interconnected to each other.
03:48
Electron transport chain occurs in the inner mitochondrial membrane...
