Which of the following events is a part of the light reaction of photosynthesis ?
a - production of carbohydrates
b - splitting up of the water molecules
c - release of the carbon dioxide.

B

Explanation:

Photosynthesis is a unique metabolic process that occurs in the Chloroplast of autotrophs like plants. The photosynthetic process generally involves generation of food (organic) using an inorganic source (CO2) in the presence of sunlight.

Photosynthesis occurs in two major stages viz: the light stage and light independent stage. The light stage of Photosynthesis occurs in the thylakoid membrane of the CHLOROPLAST, where photons of light from the sun hits CHLOROPHYLL molecules and activates them in order to split water molecules (H2O) into electrons, oxygen and hydrogen ions. This splitting of water is called PHOTOLYSIS.

answer: 21
