Answer: False

Step-by-step explanation:

The given statement is False.

The light reaction begins in photosystem 2 (PS2).

In the process of light reactions in photosynthesis energy is generated so that it can be use in the dark reactions.

During light reaction, water molecule breaks down into oxygen molecule and an electron. this free electron attains attains a higher energy level in the reaction center of photosystem 2. The state of an unstable electron undergoes an electron transport chain (ETC). The electron flows from PS2 to cytochrome and then to photosystem 1 (PS1). In PS1 the light-independent energy takes place where further electrons are transfered to NADPH.
