how is light energy converted into chemical energy during photosynthesis?

Answer 1

light is captured by the chlorophyll in the chloroplasts of plant cells. its somewhat complicated ...
each thylakoid membrane is made of photosystem I and II. light hits photosystem II first, and the plant uses a water molecule and breaks it up. the released e- is used to boost it up to the ETC (electron transport chain) where ATP is produced. the energy is moved to photosystem I which absorbs a different wavelength of light and it falls down the ETC to form NADP+ reluctase and ATP which is then used by the Calvin's Cycle. the calvin cycle uses CO2 from the envioroment and uses the NADP+ and ATP created by the light reaction to form NADPH and sugar through carbon fixation and reduction.

thus, light energy is converted into chemical energy (glucose)

sorry for my word choice, i really cant think of another way to say it.

Answer 3

After absorption of light energy by chlorophyll, the absorbed energy convert ADP into ATP also NADP into NADPH2. ATP and NADPH2 are the high energy compound, the energy of these compound used in the dark phase of photosynthesis to reduce Carbon di oxide to form Carbohydrate.
