Photosystems in Light Reaction

Question

What are the two types of photosystems involved in the light reaction of photosynthesis?

NEET Faculty · Answer

The two types of photosystems involved in the light reaction of photosynthesis are:

Photosystem I (PSI): Contains chlorophyll a molecule P700 as its reaction center
Photosystem II (PSII): Contains chlorophyll a molecule P680 as its reaction center

These photosystems work together to capture light energy and convert it into chemical energy during the light-dependent reactions of photosynthesis.
