In plants, light energy is transformed into the chemical energy of the molecules formed
during photosynthesis.
These molecules are used by the plant to produce ATP during respiration. The leaf is
the main photosynthetic structure. The chloroplasts are the cellular organelles within the
leaf where photosynthesis takes…

Photosynthesis is a complex metabolic pathway involving many intermediate reactions.
It is a process of energy transformation in which light energy is firstly changed into
electrical energy and then into chemical energy.
There are three main stages to photosynthesis:
Stage Process 1. Capturing light energy By chloroplast pigments such as…

The light dependent reaction of photosynthesis involves the capture of light whose
energy is used for two purposes:
- To add an inorganic phosphate molecule to ADP thereby making ATP - To split water
by the process of photolysis, into H+ ions and OH- ions
The reaction needs light energy.…

5. These hydrogen ions are taken up by an electron carrier called NADP 6. On taking up
the hydrogen ions, the NADP becomes reduced 7. The reduced NADP then enters the
light-independent reaction along with the electrons from the
chlorophyll molecules 8. The…

1. Light energy hits photosystem 2
This light energy excites the electrons and causes the chlorophyll to lose electrons
These electrons must be replaced Light energy also causes water to split into protons,
electrons and oxygen The electrons from photolysis are used to replace the electrons
lost from the chlorophyll…
