What is Photosynthesis process ?
Answers
Photosynthesis process can be divided into two stages:
Light Reaction
This reaction is a light- dependent reaction and it is needed to produce energy molecules like ATP and NADPH. This reaction occurs in the thylakoid membrane of the chloroplast where the sunlight triggers of the reaction of chlorophyll pigment.
The excited chlorophyll releases an electron which is accepted by the H2 of water after its splitting. The reactions that happen are redox reactions and ultimately lead to the production of energy molecules- ATP and NADPH which are then needed for the subsequent synthesizing reactions that occur in the dark reaction.
Dark Reaction
This reaction does not literally occur in the dark but is named so because it is independent of light. This reaction can occur both in the presence and absence of light. Due to the scientists who worked to discover this cycle, this reaction is also called as the Calvin- Benson-Bassham cycle.
This reaction occurs in the stroma of the chloroplast. This reaction uses the energy molecules generated in the light phase of photosynthesis and converts CO2 into glucose. The photosynthesis process can be summarised by the following equation:
6CO2+ 6H2O→C6H12O6+ 6O2 (in the presence of sunlight)
▶ is the biochemical process in which energy from sunlight is converted into Chemical energy by plants, algae, and then plants and other things make food.
▶It is a chemical process that uses sunlight to turn carbon dioxide into sugars that the cell can use as energy , further this energy absorbed by the green pigment chlorophyll.
▶Takes place during Sunlight.
▶Beneficial for other living organisms.
▶Chlorophyll is used to split water molecules into oxygen and hydrogen.
▶During this process oxygen gas is released and Co2 is consumed
⏩Example of photosynthesis is plants convert sugar and energy from water, air and sunlight.
