Outline the process involved in the light and dark reactions of photosynthesis.
(i) Light reaction – light energy helps in breaking down water into hydrogen ions, oxygen and electrons. The reaction can also be referred to as photolysis of water.
(ii) Dark reaction – in dark reaction, carbon dioxide reacts with hydrogen in a complex series of small steps, each controlled by specific enzymes; producing glucose. The reaction can take place at night or in the day time.
