प्रश्न
The reactions of photosynthesis make up a biochemical pathway.
What is the end product of light and dark reactions of photosynthesis?
उत्तर
The reaction of photosynthesis can be grouped into two: Light and Dark reactions.
The reaction involving pigments, solar energy, and water that produce ATP and NADPH2 is called a light reaction.
The photosynthetic reactions in which CO2 is reduced to carbohydrates making use of ATP and NADPH2 generated by light reaction are called dark reaction.
The overall reaction of photosynthesis can be written as follows:
\[\ce{CO2 + H2O ->[Solar energy][chlorophyll]C6H12O6 + H2 + O2↑}\]

A healthy croton plant bearing variegated leaves was kept in a dark cupboard to destarch it after which it was placed in sunlight for a few hours. One of the leaves was then plucked and an outline of the leaf marking the green and the non-green regions was drawn. The leaf was then tested for starch. Using the above information, answer the following questions:

A candidate in order to study the importance of certain factors in photosynthesis took a potted plant and kept it in the dark for over 24 hours. Then in the early hours of the morning, she covered one of the leaves with black paper in the center only. She placed the potted plant in the sunlight for a few hours, and then tested the leaf which was covered with black paper for starch.
