Question

What role does water play in photosynthesis? Water behaves as a pigment in chloroplasts to absorb light. Water acts as an electron acceptor in the formation of glucose. Water reacts with oxygen to convert light energy to chemical energy. Water is a product formed from the reaction of carbon dioxide with glucose. Water provides hydrogen and electrons used in producing glucose.

Answer 1

Answer:

Water provides hydrogen and electrons used in producing glucose.

Explanation:

Photosynthesis is process peculiar to green plants and other organisms like algae and some bacteria. Plants synthesize their own food in form of an organic molecule (glucose) by combining carbondioxide (CO2) and H2O in the presence of sunlight. They absorb light energy from the sun to power the first process called LIGHT stage, where NADPH and ATP are produced to be used in the next stage. The electrons used to reduce NADP to NADPH comes from the "PHOTOLYSIS OF WATER"

CO2 is absorbed via the stomata in the leaves of plants. The CO2 is then fixed in the stroma of the CHLOROPLAST when it undergoes series of reactions in the Calvin cycle to produce glucose. However, the glucose molecule (C6H12O6) contains hydrogen which CO2 does not possess, this Hydrogen is provided by water during the light stage where it donated it to NADP+
