With wet beriberi, peripheral vessels dilate and cardiac muscle looses its contractility. also, alpha-ketoglutarate is found in high concentrations. this is thought to be caused by:
a. excess energy production
b. a deficiency of thiamine
c. the inhibition of citrate synthase
d. a deficiency of pyridoxine
e. an excess of essential fatty acids
