Contrast an electron carrier and a terminal electron acceptor. Although physiologically distinct, lithotrophs and organotrophs share a number of features in common with respect to ATP production. Pyruvate is an important intermediate in both catabolism and anabolism. Describe one catabolic reaction in which pyruvate serves as a key intermediate. Describe an anabolic reaction in which pyruvate is a key intermediate.
