A) \[\text{PS-I}\]
B) \[\text{PS-II}\]
C) Hill reaction
D) None of these
Correct Answer: B
Solution :
Photosynthesis is driven by two photochemical processes. These processes are associated with two groups of photosynthetic pigments called as pigment system-I and pigment system-II. [a] PS-I-It is located on both-the non-appressed part of grana thylakoids as well as stroma thylakoids. In green plants, PS-I contains more of chlorophyll-\[a\] photocentre is a special chlorophyll-\[a\] molecule called \[{{\text{P}}_{\text{700}\text{.}}}\] [b] PS-II-It is a photosynthetic pigment system alongwith some electron carriers that is located in the appressed part of the grana ihylakoids. The PS-II contains chlorophyll\[-b.\] and some forms of chlorophyll\[-a.\] A very small amount of special form of chlorophyll-a is called \[{{\text{P}}_{\text{680}}}\] constitute the reaction centre of pigment system-II.
