The photosynthetic reactions convert light energy into chemical energy, which is stored in molecules like atp. in the photosynthetic reactions, this energy is used to convert co2 into carbon sugars.
a) light dependent; chloroplast
b) chloroplast; light independent
c) light dependent; light independent
d) light independent; light dependent

C

Explanation:

light-dependent reactions require sunlight. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of the electron carrier molecule NADPH (nicotinamide adenine dinucleotide phosphate) and the energy currency molecule ATP (adenosine triphosphate). The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast.

While In the light-independent reactions, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.

So the answer is definitely C
