Tardigrade Admin · Accepted Answer

PS I and PS II are two types of photosystems. The photosystem PS II is known for absorbing red light at 680 nm and thus its reaction centre is P680 while PS I absorbs red light at wavelength 700 nm and has reaction centre P700.PS I is present on outer surface of thylakoid membrane and PS II on inner side of the thylakoid membrane. During non-cyclic photophosphorylation or Z scheme product produced by PS I is NADPH and product produced by PS II is ATP along with hydrolysis of water.
