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.

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.

Insulin helps a cellular pump work better when fuel levels are low, but doesn’t make it go faster when everything’s already maxed out — it’s like giving the pump a sensitivity boost, not a power upgrade.

Insulin doesn't boost the pump activity in frog muscle cells when it's already running at full speed, which suggests insulin helps the pump respond better to signals instead of making it work harder.

Insulin can boost a tiny cellular pump in frog muscle cells, and it works way better when certain conditions like low salt or energy levels are present.

When you eat, your body releases insulin, which helps muscle cells pull more potassium from your blood by putting more pumps on their surface—this keeps your muscles working smoothly after meals.
