Question

Chemical formula of light and dark reaction of photosynthesis.

Answer 1

Hi..

➡️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..

➡️Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls..

➡️Carbon fixation is an endothermic redox reaction. In general outline, photosynthesis is the opposite of cellular respiration; in the latter, glucose and other compounds are oxidized to produce carbon dioxide and water, and to release chemical energy (an exothermic reaction) to drive the organism's metabolism..

➡️The equation for photosynthesis states that the combination of carbon dioxide, water and light energy produces a carbohydrate (glucose) and oxygen. The chemical formula is 6CO2 + 6H2O + light energy = C6H12O6 + 6O2...

Hope this helps u!
