Photosynthesis Steps Table

Step Number	Process	Description
1	Light Absorption	Chlorophyll in plant cells absorbs sunlight, providing the energy needed for photosynthesis.
2	Water Splitting	Water molecules are split into oxygen and hydrogen ions, releasing oxygen as a byproduct.
3	ATP and NADPH Production	The energy absorbed from light is used to convert ADP to ATP and NADP+ to NADPH, providing energy carriers for later steps.
4	Carbon Dioxide Fixation	Carbon dioxide from the air is attached to a five-carbon sugar (RuBP) in the Calvin cycle.
5	Reduction Phase	ATP and NADPH are used to convert the carbon dioxide and RuBP into glyceraldehyde-3-phosphate (G3P), a three-carbon sugar.
6	Regeneration of RuBP	Some G3P molecules are used to regenerate RuBP, enabling the cycle to continue.
7	Glucose Formation	The remaining G3P molecules are used to form glucose and other carbohydrates, which are used as energy sources or structural materials in the plant.
