Question

What primarily happens during the light-dependent reactions of photosynthesis? What 2 reactions does solar energy drive during this stage? Likewise, what primarily happens during the Calvin Cycle? What's the name of the enzyme that directs this reaction, and what are its normal substrates?

Answer 1

Answer:

During light reaction of Photosynthesis ATP and NADPH are formed.

Explanation:

Reactions driven by solar energy

      H2O=H+  +   OH-

       4OH-   - 4e-  =4OH

        4OH=2H2O+O2

Second reaction

NADH+e- +H+=NADPH

Carbon dioxide fixation occurs during Calvin cycle.Carbon dioxide is being fixed into glucose molecule.

The name of the enzyme is Ribulosebisphosphate Carboxylase(RUBISCO)

The normal substrate for this enzyme is Ribulose bisphosphate(RUBP)
