What are the products of light-dependent reactions? Why are they important in light-independent reactions?
tamaranim1 [39]

The products of light-dependent reaction are ATP and NADPH. They are essentially required to fix carbon dioxide and make glucose in light-independent reactions.

Light-dependent reactions are those that use the direct sunlight energy to make usable forms of chemical energy i.e., ATP and NADPH. For this, a pigment called chlorophyll is essential that has the ability to the capture the sunlight.

Light-independent reactions are those that do not directly depend on the sunlight energy to complete their process. Instead they are dependent on the products of light reactions so that they can fix atmospheric carbon dioxide and make glucose for the plant. Calvin cycle is the main process of light-independent reaction.

One of the accepted scientific theories describing the origin of life on Earth is known as chemical evolution. According to this
Natali [406]

Answer:

C. Synthesis of organic molecules

Explanation:

According to chemical evolution theory, life originated from inorganic molecules by the mode of chemical evolution. In primitive conditions of earth, only inorganic molecules were present. These molecules reacted under lightning, UV radiation and other environmental conditions to give rise to complex organic molecules like amino acids, sugars, lipids etc. They formed the basis for proteins, RNA and other molecules which ultimately led to the formation of cellular structures.
