An exothermic chemical reaction is change in the chemicals that can never be undone, an exothermic solution is a combination of chemicals
<span>How are the dark reactions that occur in plants dependent on the light reactions?
a.The chemical energy used in the dark reactions is produced in the light reactions.
Photosynthesis is divided into two parts.
1) Light - dependent reaction
2) Light - independent reaction
Light dependent reaction absorb energy from the sun to produce ATP and NADPH, these energies are used in the light-independent reaction. The ATP provides the energy, while the NADPH provides the electrons required to fix the carbon dioxide into carbohydrates.

It is a covalent substance because there is a covalent bond between Hydrogen and Oxygen
