What is the role of blue light in terms of stomatal study?
a.) Blue light activates a proton-pumping ATPase in the guard cell plasma membrane and leading to stomatal opening
b.) blue-light stimulation lowers the pH of the apoplastic space surrounding the guard cells, and generates the driving force needed for ion uptake and stomatal opening
c.) The sensitivity of guard cells to blue light increases as a function of their zeaxanthin concentration
d.) npq1 mutant opens at higher fluence rates of blue light, whereas the phot1/phot2 mutant fails to show any blue light–stimulated opening

Pyruvate is coverted into the Acetyl-CoA, Acetyl-CoA contain the acetyl group which are comes from the pyruvate and Coenzyme A (CoA) that contain other groups such as;
a) A reactive thiol (—SH) group that is critical to the role of CoA as an acyl carrier in a number of metabolic reactions
b) contain pantothenic acid, A hydroxyl group of pantothenic acid is joined to a modified ADP moiety by a phosphate ester bond
c) pantothenic acid carboxyl group is attached to β-mercaptoethylamine in amide linkage
d) Hydroxyl group at the 3’ position of the ADP moiety has a phosphoryl group not present in free ADP
