Vedclass · Answer

(B) Bacteriochlorophyll is a photosynthetic pigment found in certain bacteria. It differs from chlorophyll $a$ primarily in the structure of its porphyrin ring. In bacteriochlorophyll,one of the pyrrole rings (specifically ring $I$) is reduced,meaning it contains two additional hydrogen atoms compared to the corresponding ring in chlorophyll $a$. Therefore,the presence of a pyrrole nucleus containing two hydrogens (a reduced pyrrole ring) is the key structural difference.

Bacteriochlorophyll differs from chlorophyll $a$ due to the presence of:
