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*→pheophytin→ plastoquinones→ 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*→ plastoquinones → pheophytin → cytochrome b6 f complex→ plastocyanin→ in turn reduces (PSI) P700+

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
Which of the following combinations from the above statements is correct?
