Answer;
The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.
Explanation;
-Photosynthesis is the process by which green plants use light energy from the sun, water and carbon dioxide to make organic molecules, such as simple sugars.
-The process takes place in two phases; light dependent stage and light independent stage.
-During light dependent stage light energy is used to break down water molecules into hydrogen ions and oxygen atoms.
-Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. ATP is used to provide the energy for sugar synthesis and NADPH is used for electrons in the reduction of Carbon Dioxide into sugar.
