Membrane transport as controlling pacemaker of glycolysis in Saccharomyces carlsbergensis

The frequency of anaerobic NADH oscillations in Saccharomyces carlsbergensis following addition of fructose is 1.5–2.0 times slower than that following addition of glucose. Since catabolism of the two sugars differs in the sugar phosphorylation pathway only, the reason for the observed alternation of the frequency must be sought among these reactions. It has been found that:

1.

1. The equilibrium of hexose phosphates, as catalized by phosphoglucose isomerase, is nearly independent of the added hexose.
