Electrons ejected from chlorophyll travel through a series of electron carriers organized in the “Z Scheme” shows a current version of the Z scheme, in which all the electron carriers known to function in electron flow from H2O to NADP Presented in the following sequence;

a.) P680 reduce by Yz has received electrons from oxidation of water P680→P680*→pheophytinplastoquinones→ cytochrome b6 f complex→ plastocyanin→ in turn reduces (PSI) P700+

b.) P700+→ P700*→ membrane-bound iron–sulfur proteins → A0→ A1 → flavoprotein ferredoxin–NADP reductase (FNR) soluble → ferredoxin(Fd) → NADP+ to NADPH

c.) P700+→ P700*→ A0→ A1→ membrane-bound iron–sulfur proteins→ ferredoxin(Fd)→ soluble flavoprotein ferredoxin–NADP reductase (FNR)→ NADP+ to NADPH

d.) P680 reduce by Yz has received electrons from oxidation of water P680→P680*→ plastoquinonespheophytin → cytochrome b6 f complex→ plastocyanin→ in turn reduces (PSI) P700+

If a given lymphocyte divides to form two daughter cells, both daughters bear antigen receptors with antigen specificities identical to each other and to the parental cell from which they arose, and so will any descendants they produce. The resulting population of lymphocytes, all arising from the same founding lymphocyte, is a clone. Which interleukin is responsible for clone production?

The role of N-terminus and the C-terminus region of the cryptochrome is given below;

a) N-terminal region is involved in the dimerization of cryptochrome and conformational changes

b) C terminus of cryptochrome forms a complex with SPA1 and COP1 that prevents them from acting, thereby preventing the degradation of HY5

c) N-terminal region of cryptochrome forms a complex with SPA1 and COP1 that prevents them from acting, thereby preventing the degradation of HY5

d) Arabidopsis plants overexpressing only the C-terminal region of cryptochrome (CCT) which resemble light-grown seedlings when grown in darkness
