Hello students, the concept given in the question is photosynthesis.
00:07
It is an image -based question.
00:10
What is required for us is to aptly fill the blocks here, which has been given in the organal chloroplast.
00:19
Okay, let us get into the explanation.
00:22
Well, photosynthesis taking place in higher plants, it is involved in an organol called as chloroplast.
00:31
So inside chloroplast, photosynthesis takes place in higher plots.
00:38
Otherwise, if there is only presence of chlorophyll itself, photosynthesis takes place in lower plants.
00:45
So inside the chloroplasts, two such processes takes place, nothing but light reaction and dark reaction.
00:53
In light reaction, it involves the functioning of various photosystems.
00:58
There are two photo systems chiefly which is involved one and two.
01:03
So here the solar energy is observed, converted into electrons, and in this entire reaction, there is production of atp and nadph also.
01:21
So atp as the source of energy from adp and nadph as the reduced co -enzyme.
01:29
From nad.
01:32
Okay.
01:33
So that is what happens in light reactions, takes place in the presence of light.
01:37
Now in the dark reaction, what happens, these both atp and med to h is utilized in fixing carbon dioxide into sugars.
01:48
This dark reaction takes place in the stroma of chloroplast and light reaction takes place in the granar, the membranal system of the chloroplast.
01:58
Now knowing this piece of information, let us fill in the blocks.
02:04
And one more thing what is very important here is, during light reaction there is a release of oxygen on photolysis of water.
02:14
So here the protons from the water is being taken or broken down and the electrons released on that process is utilized by the photo systems...
