Light reactions and Calvin Cycle

Explanation:

The products of the light reaction become the products of the Calvin cycle (which is the dark stage) of photosynthesis. The light reaction is called so because it harnesses the energy of the sunlight photons to split water molecules into H+ and O- . The CO2 is then reduced to glucose using the H+ in the Calvin cycle without the need for sunlight - hence referred to as the dark reaction. The light reaction occurs in the grana while the dark reaction occurs in the stroma.

weathering is the answer.

the backbone of the dna and rna compound is sugar phosphate.
