Hello students here many questions are asked in the first question they have asked about the role of nad ph in photosynthesis.
00:14
The correct answer for this question is option c it carries electrons to calvin cycle in the second question they have given the equation of cellular respiration and have asked what happens to the carbon atom of sugar and molecular oxygen.
00:44
In the process of respiration sugar is oxidized to form carbon dioxide while the oxygen is reduced to form water.
01:12
In the next question, they have asked why are the leaves of a tree red orange and yellow in the fall the correct answer for this question is option b plants do not produce chlorophyll in the weather and any chlorophyll present will break down so that it is no long hides the carotenoid pigment.

In the next question they have asked, when we measure in chloroplast, the amount of atp and nadh consumed by calvin cycle in 1 hour is 30 ,000 molecules of atp.
02:24
But only 20 ,000 molecules of nadh are consumed.
02:29
They have asked to explain where did the extra atp molecules come from.
02:33
The extra atp molecules come from the cyclic electron though which is given as option c.
02:46
In the next question they have asked accessory pigments within chloroplast are responsible for which function.
02:55
The correct answer for this is option d.
02:57
They are responsible for extending absorption spectrum of chlorophyll a so it can absorb more photons.
03:23
In the next question, they have asked to select the pathway which most electrons follow inside an active mitochondria...
