1. Electron transfer: The absorbed light energy is transferred to a special molecule called an electron acceptor, which then passes the energy on to a series of electron carriers.

How Does it Work?

So, what exactly happens during light-dependent reactions? In simple terms, light-dependent reactions occur when light energy is absorbed by pigments in the thylakoid membrane of a plant's chloroplast. This energy is then transferred to a special molecule called ATP (adenosine triphosphate), which is used to power the plant's metabolic processes. The light-dependent reactions involve two main stages: the absorption of light energy and the transfer of electrons. This process is crucial for the plant's survival, as it allows them to convert sunlight into energy.
