$P_{700}$ and $P_{680}$ are the reaction centres of $PS-I$ and $PS-II$ respectively.

Vedclass · Answer

(D) In $PS-I$,the reaction centre is a special chlorophyll-a molecule called $P_{700}$,which absorbs light at $700 \; nm$. In $PS-II$,the reaction centre is a special form of chlorophyll-a called $P_{680}$,which absorbs light at $680 \; nm$. Option $D$ states $P_{700}$ and $P_{680}$ are reaction centres of $PS-I$ and $PS-II$ respectively,but the original text provided in the option had typos ($P_{\infty 0}$ and $P_{\pi x}$). The statement is factually correct,but the notation in the provided option $D$ was incorrect. However,all statements $A, B, C$ are standard descriptions of light reactions. Given the context of typical biology questions,if one must be 'not true',it usually refers to a factual error in the statement. Since $A, B, C$ are correct,and $D$ contains typographical errors in the prompt,$D$ is the intended answer.
