The Claim
Insulin stimulates (Na+ + K+)-ATPase activity in isolated frog skeletal muscle membranes, but only under specific submaximal ionic and substrate conditions (10 mM K+, 0.5 mM ATP, 4 or 25 mM Na+), indicating that the effect of insulin on this enzyme is context-dependent and not universally observed across all biochemical environments.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Insulin can boost a tiny cellular pump in frog muscle cells, but only when the salt and energy levels are just right — it doesn’t work all the time, just in specific situations.
See the scientific wording
The (Na+ + K+)-ATPase in isolated frog skeletal muscle membranes is stimulated by insulin only under specific submaximal ionic and substrate conditions (10 mM K+, 0.5 mM ATP, 4 or 25 mM Na+), indicating that insulin's effect is context-dependent and not universal across all biochemical environments.
What the research says
1 studyStudy: Effect of insulin upon membrane‐bound (Na+ + K+)‐ATPase extracted from frog skeletal muscle.
The study shows insulin only boosts a key muscle enzyme when conditions are just right, not all the time, which matches the claim.
