Photosynthesis in Higher Plants

The leaves of $C_4$ plants show Kranz anatomy, with mesophyll cells and large bundle sheath cells around the vascular bundles.
In $C_4$ plants the $C_4$ cycle occurs in the mesophyll cells and the $C_3$ (Calvin) cycle occurs in the bundle sheath cells.
The primary $CO_2$ acceptor, phosphoenol pyruvate (PEP), is present in the mesophyll cells, where the enzyme PEP carboxylase fixes $CO_2$ to form oxaloacetic acid (OAA).
OAA is then reduced to malic acid (or converted to aspartic acid) in the mesophyll cells themselves.
The malic acid is transported to the bundle sheath cells, where it is broken down to release $CO_2$ for the Calvin cycle.
So malic acid formation occurs in the mesophyll cells.

In photosystem II the reaction centre chlorophyll a (P680) absorbs light of 680 nm and its electrons become excited.
The excited electrons are picked up by an electron acceptor and passed to an electron transport system.
The electron passes through pheophytin to the quinones: the bound plastoquinone QA, then QB and the mobile plastoquinone pool. Among the given choices the first acceptor is quinone.
From plastoquinone the electrons pass to the cytochrome b6-f complex, then to plastocyanin and to photosystem I.
The iron-sulphur protein and ferredoxin are electron acceptors on the reducing side of photosystem I, not photosystem II.
Cytochromes come after the quinone in the chain.
So the first acceptor of electrons from the excited chlorophyll of photosystem II is quinone.
