Question

The radiant energy is stored in the form of chemical energy in
A. DNA
B. Stored food
C. RNA
D. ATP

Answer 1

In plants, the radiant energy from the sun will be converted into chemical energy to that of glucose (sugar). This transformation is called photosynthesis. Plants use water, carbon dioxide, and sunlight and transform these into oxygen and glucose.

Complete answer: Plants are capable of utilizing and exploiting energy from the sun in a method called photosynthesis. They receive radiant energy from sunlight and convert it into useful chemical energy trapped in molecules within their cells. Radiant energy refers to the energy present in the electromagnetic wave. The hot objects emit IR radiation, and so this transfer of radiant energy enables the hot object to reduce heat energy and other surrounding objects to acquire heat energy. Chemical energy is the energy trapped in a chemical bond between atoms.
6 H$_2$O + 6 CO$_2$ + Sunlight = C$_6$ $H_{12}$O$_6$ + 6O$_2$
So, the correct option is (B).
Additional Information:
Photosynthesis is a process plant and also some algae have been used to process light energy into chemical energy processed as sugar in chloroplasts — energy plants found in plant cells. In the form of energy-transduction reactions, conversion of solar energy into chemical energy in the form of two energy-transporting molecules, ATP and NADPH. As solar radiation hits plant cells and activates unique chlorophyll molecules, it generates a high-energy electron. The emission of this electron starts a series of electron-trading and energy-transferring activities between many intermediate molecules, and the last molecule to shape and maintain the electrons in this sequence is NADPH. The electrons of the excited chlorophyll molecule have to be replaced, and these electrons originate from water. With the assistance of enzymes and solar energy, water is differentiated into electrons, protons, and oxygen. The electrons go to chlorophyll, whereas the protons contribute to the proton gradient which is used to produce the production of the second energy-carrying molecule, ATP. Oxygen is just the-product of this process. The chemical energy in NADPH and ATP is used to power phases in subsequent carbon-fixing processes.

Note: Usually, radiant energy corresponds to sunlight. Photosynthesis is indeed an example of the processing of radiant energy into chemical energy as a correlation between hydrogen, oxygen, and carbon. Light energy is transformed into chemical energy whenever the photo-chemically stimulated specific chlorophyll molecule of the photosynthesizing reaction Centre loses electrons, which is experiencing an oxidation process.
