In the synthesis of prostaglandins and thromboxanes

A) arachidonic acid of the cytosol serves as the primary precursor.
B) PG synthase uses 2 molecules of oxygen to generate the endoperoxide PGG₂.
C) PGE₂ synthesis would be inhibited by aspirin but thromboxane synthesis would not be affected.
D) PGH₂ is the precursor of PGE₂ but PGI₂ is the precursor of TXA₂.
E) all tissues have the capacity to synthesize all of the prostaglandins.
