Specifically, this refers to the light-dependent reactions of photosynthesis. Here's a breakdown:
* Sunlight provides the energy for the reaction.
* Chlorophyll in the chloroplasts of plants captures this light energy.
* Water is split, releasing oxygen as a byproduct.
* Electron carriers (NADPH and ATP) are produced, storing the captured light energy.
These carrier molecules are then used in the light-independent reactions (Calvin Cycle) to convert carbon dioxide into glucose, the primary energy source for plants and ultimately, for most life on Earth.
So, in essence, sunlight is used to power the production of ATP and NADPH, which act as "energy carriers" to fuel the subsequent production of glucose in photosynthesis.
