Answer:
Photosynthesis is the process with which plants transform sunlight into nutrients. It takes place within the thylakoids membrane and stroma of the plant’s chloroplast.
Photosynthesis can be broken down into 2 reactions:
1.) Light-dependant reaction- reaction that requires sunlight and occurs in the thylakoids of the chloroplast.
Reactants: H2O (water), sunlight, NADP+, ADP, and +Pi —> Products: O2, ATP (energy), and NADPH.
2.) Light-independent reaction (aka Calvin Cycle)- reaction that occurs in the stroma of the chloroplast and does not require sunlight because ATP (energy) was formed in the previous reaction.
Reactants: CO2, ATP (energy), and NADPH —> Products: CH2O, NADP+, ADP, +Pi
SO the main reactants of photosynthesis are Light, H2O (water), and CO2 —> the main products of photosynthesis are O2 and CH2O
