The structure of the four major protein complexes in the thylakoid membrane are organised form such as ;

a.) PSII is located predominantly in the stacked regions of the thylakoid membrane and Cytochrome b6f complexes are evenly distributed

b.) PSI and ATP synthase are found in the unstacked regions protruding into the stroma

c.) Lateral separation of the two photosystems requires that electrons and protons produced by PSII be transported directly to PSI and the ATP coupling enzyme

d.) Four main protein complexes of the thylakoid membrane, shown also are the two diffusible electron carriers—plastocyanin, which is located in the thylakoid lumen, and plastohydroquinone (PQH2) in the membrane, The lumen has a positive electrical charge with respect to the stroma

Fever is an abnormal elevation of body temperature. Following statements are regarding to the cellular mechanism of fever.
A. Pyrogens produce fever by increasing the hypothalamic set-point temperature.
B. the mechanism of pyrogen action is increased production of interleukin-1 (IL-1) in phagocytic cells.
C. IL-1 then acts on the anterior hypothalamus to increase local production of prostaglandins, which increase the set-point temperature.
D. IL-1 then acts on the posterior hypothalamus to increase local production of prostaglandins, which increase the set-point temperature.
E. IL-1 then acts on the posterior hypothalamus to increase local production of prostaglandins, which decrease the set-point temperature.
