light reaction

• Fase inicial da fotossíntese, na qual a energia luminosa é absorvida pela clorofila e convertida em energia química, com produção de ATP e NADPH.

The initial stage of photosynthesis in which light energy is absorbed by chlorophyll and converted into chemical energy, producing ATP and NADPH.

1. Photosynthesis stageC1formal

   The first stage of photosynthesis where light energy is converted into chemical energy (ATP and NADPH).

   Fase clara

   • The light reaction occurs in the thylakoid membranes of chloroplasts.
   • During the light reaction, water molecules are split to release oxygen.
   • ATP and NADPH produced in the light reaction are used in the Calvin cycle.
