Detailed explanation-1: -Photosystems are structures within the thylakoid membrane that harvest light and convert it to chemical energy. Each photosystem is composed of several light-harvesting complexes that surround a reaction center.
Detailed explanation-2: -After the photon hits, photosystem II transfers the free electron to the first in a series of proteins inside the thylakoid membrane called the electron transport chain.
Detailed explanation-3: -The hydrogen ions are allowed to pass through the thylakoid membrane through an embedded protein complex called ATP synthase. This same protein generated ATP from ADP in the mitochondrion.
Detailed explanation-4: -Photosystem II (PSII) and PSI are integral thylakoid membrane protein complexes each consisting of numerous distinct polypeptides (Fig. 17.2).
Detailed explanation-5: -Two enzymes present at significant levels in the preparations are polynucleotide phosphorylase and adenylate kinase.
