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

The following statements are related to pentose phosphate pathway.
a) The first and third steps are oxidations with large, negative standard free-energy changes and are essentially irreversible in the cell
b) NADPH rises and inhibits the first enzyme in the pentose phosphate pathway. As a result, more glucose 6-phosphate is available for glycolysis
c) All the enzymes of the reversible reaction of the pentose phosphate pathway are located in the cytosol
d) The NADPH is used for biosynthetic reactions such as lipid synthesis and nitrogen assimilation in the cytosol
which one of the following combination of above statements is incorrect?
