The Claim

In isolated frog skeletal muscle membranes, insulin stimulates (Na+ + K+)-ATPase activity, and this stimulation is completely inhibited by 10⁻³ M ouabain, demonstrating that insulin's effect is specific to the ouabain-sensitive component of (Na+ + K+)-ATPase rather than non-specific ATPase activity.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Insulin boosts a specific cellular pump in frog muscle cells, but this boost gets completely stopped by a chemical called ouabain — meaning insulin only affects that particular pump, not others.

See the scientific wording

The stimulatory effect of insulin on (Na+ + K+)-ATPase in isolated frog skeletal muscle membranes is completely blocked by ouabain at 10⁻³ M, indicating that insulin's action is specific to the ouabain-sensitive (Na+ + K+)-ATPase component rather than non-specific ATPase activity.

What the research says

1 study
  1. Study: Effect of insulin upon membrane‐bound (Na+ + K+)‐ATPase extracted from frog skeletal muscle.

    The study shows that insulin boosts a specific cell pump in frog muscle, and this boost is completely stopped by a blocker called ouabain, meaning insulin works only on that specific pump.
