      Photosynthesis involves 2 stages - the Light-dependent Stage and the Light-independent stage. In the light-dependent stage, water is photolyzed by sunlight into Hydrogen and oxygen. Hydrogen enters the second stage, oxygen is gaseous by-product. In the light - independent stage enzymes are catalyzed the reduction of carbon dioxide by hydrogen.

      1. The light-dependent stage of photosynthesis takes place on thylakoid membranes in chloroplasts. These membranes surround the thylakoid space (lumen) and are arranged into stacks known as grana. Below is a diagram showing the arrangement of photosystems in the thylakoid membrane, and summarising the processes that take place there. light ...

      stage is the light-dependent reaction, (see below) during which energy from sunlight is captured and converted to chemical energy, in the form of ATP and NADPH. In this step, water molecules (H 2 O) are broken apart, releasing electrons and hydrogen ions for use in stage two of photosynthesis, and releasing oxygen as a waste gas. Oxygen

      Thefirst hypothesis abouttherole of light in photosynthesis came very appropriately from Jan Ingenhousz, who some years earlier had madethe epochal discovery that it is "the influence of the light of the sun upon the plant" (1) that is responsible for the "restorative" effect of vegetation on "bad" air-an observation first made in 1771 by Joseph
