Question

Light reaction dark reaction in short cut

Answer 1

in plants

in light reaction plants do phothosyntsis and prepare food

in dark reaction plants use oxygen and break down moliqules of gulocose

Answer 2

The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP..Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates
