Table 2. Effects of glucose and MeS on the ATP/ADP ratio in rat and mouse islets.

Values are means±S.E.M. for four independent experiments. Islets were prepared as described in Table 1. Control continued incubation in 4 mM glucose and did not change between 1 and 5 min. Control values are averages over all time points.

	ATP/ADP ratio (rat)			ATP/ADP ratio (mouse)

Glucose (4 mM)	4.4±0.2			2.7±0.1
Glucose (10 mM)	6.7±0.6	7.1±0.4	8.1±0.6	4.5±0.2	5.2±0.1	4.8±0.3
