Question

Explain the process of photosynthesis and the light and dark reactions

Answer 1

Answer:

Photosynthesis: is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy.  

This process is extremely important for life on earth as it provides the oxygen that all other life depends on.

Light reactions :need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls.

Dark reactions: make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma.ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.

Explanation:

Answer 2

Answer:

in stoma enzymatic reaction synthesizer suger which is turn form starch the former set of reaction in photosynthesis directly light driven so it is called light reaction or the photochemical reaction.

, the letter fees of reaction are not directly life driven but are dependent on the product of light reaction like ATP and NADPH to distinguish the letter there called as dark reaction of the carbon reaction. this reaction only occur in darkness they are not light dependent.
