2. Figure 1
Sodium (Na)/citrate cotransporter activity was determined in adult (□) and infant (■) rats. Na-dependent (left bars) and Na-independent (right bars) 14C-citrate uptake was determined in renal cortical brush border membrane vesicles (N = 6).

3. Figure 2
Citrate synthase activity in adult and infant rats. Citrate synthase activity was determined spectrophotometrically as the appearance of CoA from acetyl CoA and oxaloacetate in mitochondrial suspensions (N = 6).

4. Figure 3
Adenosine 5′-triphosphate (ATP) citrate lyase activity in adult and infant rats. ATP citrate lyase activity was measured spectrophotometrically as the generation of acetylhydroxamate (N = 6). *P < 0.05.

5. Figure 4
Mitochondrial-aconitase (m-aconitase) activity in adult and infant rats. m-Aconitase activity was determined spectrophotometrically as aconitate generation from isocitrate in mitochondrial suspensions (N = 6). *P < 0.05.

6. Figure 5
Renal cortical citrate concentration in adult and infant rats. Kidneys were freeze clamped in vivo, and pulverized under liquid N2. Citrate levels were measured spectrophotometrically (N = 9).
