Photosynthesis is a process that occurs in plants, algae, and some bacteria. It involves a series of complex biochemical reactions that convert light energy from the sun into chemical energy stored in organic molecules. The following are the main events that occur during photosynthesis:
Absorption of light energy: Chlorophyll and other pigments in the chloroplasts of plant cells absorb light energy from the sun.
Conversion of light energy into chemical energy: The light energy is converted into chemical energy in the form of ATP and NADPH.
Water splitting: Water molecules are split into oxygen gas and hydrogen ions in a process known as photolysis.
Carbon fixation: Carbon dioxide from the air is fixed into organic molecules like glucose through a series of enzyme-catalyzed reactions known as the Calvin cycle.
Oxygen release: During photosynthesis, oxygen gas is produced as a waste product and released into the atmosphere.
Overall, photosynthesis is a complex process that involves the conversion of light energy into chemical energy, the splitting of water molecules, the fixation of carbon dioxide, and the release of oxygen gas. This process is essential for the survival of plants and other photosynthetic organisms, and it is also responsible for producing the oxygen that makes life possible on Earth.
