Gluconeogenesis regulation

Primary signals Insulin turns off. Glucagon turns on. Acetyl-CoA turns on. Phosphorylation turns on in liver. [Pg.146]

There are two unusual aspects to the regulation of gluconeogenesis. The first step in the reaction, the formation of oxaloacetate from pyruvate, requires the presence of acetyl-CoA. This is a check to make sure that the TCA cycle is adequately fueled. If there s not enough acetyl-CoA around, the pyruvate is needed for energy and gluconeogenesis won t happen. However, if there s sufficient acetyl-CoA, the pyruvate is shifted toward the synthesis of glucose. [Pg.146]

Glucocorticoids—mainly cortisol (see p. 374)—induce all of the key enzymes involved in gluconeogenesis [4, 6, 8, 9]. At the same time, they also induce enzymes involved in amino acid degradation and thereby provide precursors for gluconeogenesis. Regulation of the expression of PEP carbo>Q -kinase, a key enzyme in gluconeogenesis, is discussed in detail on p. 244. [Pg.158]
