Table 1.

After 60 min of incubation, intermediates in glycolysis, the TCA cycle, and the pentose phosphate shunt did not affect the accumulation of ⁴⁵Ca²⁺.

Substrate	Percent of control

Gluconolactone	104 ± 6.72

Separate addition of nine different metabolites (10 mM, each) involved in three pathways dependent on G6P demonstrated that none significantly altered (p > 0.05) the accumulation of calcium. Data are presented as means of percent of control ± SEM for n =4. Each microsomal preparation contained a minimum of eight whole brains pooled together.
