Answer:
Choosing light dependent phase of the photosynthesis process.
Step-by-step explanation:
When the sunlight falls on the leaves of the plant, Light is absorbed by the leaves. The photosystem II captures or traps the photons of the light that leads to electrons of a chlorophyll in excited state with a very large energy charge.
Primary electron acceptor traps the excited electron and simultaneously electrons captured from the water as well. Electrons then move to the PSI (photosystem I) through cytochrome b6f. At the photosystem I these electrons result in the energy imbalance, the electrons that are captured by electron acceptor again that move it to ferredoxin that take them for the production of ATP to ATP synthase.
