||P.103 left column 2nd paragraph: "Approximately 20 mmol of ATP is consumed during the synthesis of 1 g of cells (wet weight)
in a growing culture of anaerobic bacteria (ref 129). The intracellular concentration of ATP is about 2 mM (Table 1). Obviously the ATP system has a catalytic role only. During the doubling of the cell mass, ATP must be turned over approximately 10,000 times." P.103 left column 4th paragraph: "The catalytic role of the adenylate system in metabolic energy transformation requires a strict coordination of ATP consumption and ATP regeneration. The adenylate energy charge [(ATP + 0.5 ADP)/(ATP + ADP + AMP)] (refs 28, 29, 31) (see Table 1) appears to be kept rather constant under different nutrient conditions (ref 130) and absolute cellular contents (ref 148, see however refs 176, 604)."
