WHAT IS PHOTOSYNTHESIS?
Plants, algae, and other chlorophyll-bearing organisms capture light energy and use it to produce food. This energy is passed on to animals that feed directly on plants or on other animals that have fed on plants. The entire process of capturing light energy to produce food is called photosynthesis.
The equation is:6CO2 + 6H2O + light chlorophyll -> C6H12O6 + O6
JOHN FLORENTINO E. ECHON, TNHS
REMEMBER
In the light-dependent process, light strikes chlorophyll in such a way as to excite electrons to a higher energy state. In a series of reactions, the energy is converted (along an electron transport
process) into ATP and NADPH. Water is split in the process, releasing oxygen as a by product of the reaction. The ATP and NADPH are used to make C-C bonds in the dark reaction. The photosynthetic process, in which food(sugar) molecules are
formed from the carbon dioxide in the atmosphere with the use of ATP can occur in the dark as long as ATP is present.
Photosynthesis is two stage process. The light reaction that took place in the grana of the chloroplast and the dark
reaction that took place in he stroma of the chloroplast.
