Energy partitioning between two photosystem protects them from quick dessipation or quick inactivation this energy partitioning take place by a protein kinase that can phosphorylate a specific threonine residue on the surface of LHCII, what is the role of LHCII in phosphorylated and non-phosphorylated state?
a.) LHCII in phosphorylated state migrate towards the PSI in the unstacked region and delivers energy to the PSI
b.) LHCII in nonphosphorylated state moves back to the grana and delivers energy to the PSII
c.) LHCII in phosphorylated state migrate towards the PSII in the stacked region and delivers energy to the PSI
d.) LHCII in nonphosphorylated state moves towards the stroma lamellae unstacked region and delivers energy to the PSII

Fossils of Lystrosaurus, a dicynodont therapsid, are most common in parts of modern-day South America, South Africa, Madagascar, India, South Australia, and Antarctica. It apparently lived in arid regions, and was mostly herbivorous. It originated during the mid-Permian period, survived the Permian extinction, and dwindled by the late Triassic, though there is evidence of a relict population in Australia during the Cretaceous. The dicynodonts had two large tusks, extending down from their upper jaws; the tusks were not used for food gathering, and in some species were limited to males. Food was gathered using an otherwise toothless beak. Judging from the fossil record, these pig-sized organisms were the most common mammal-like reptiles of the Permian. Anatomically, what was true of Lystrosaurus?
