Vedclass · Answer

(B) In photosystem $II$ $(PS \ II)$,the reaction center is $P680$,which means it consists of chlorophyll $a$ molecules that have an absorption peak at $680 \, nm$.This wavelength of $680 \, nm$ falls within the red region of the visible light spectrum.When these chlorophyll $a$ molecules absorb light at this specific wavelength,the electrons in the pigment molecules become excited and jump into a higher energy orbit,initiating the electron transport chain.

In photosystem $II$,the reaction center chlorophyll $a$ absorbs $680 \, nm$ wavelength of ...... causing electrons to become excited and jump into an orbit.
