The Claim
In African clawed frogs (Xenopus laevis), severe dehydration significantly alters the kinetic properties of liver pyruvate kinase while having no significant effect on the kinetic properties of muscle pyruvate kinase.
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.
In African clawed frogs, severe dehydration changes how the liver enzyme pyruvate kinase functions, but does not change how the same enzyme functions in muscle tissue.
See the scientific wording
In African clawed frogs (Xenopus laevis), liver pyruvate kinase kinetics are significantly altered by severe dehydration, while muscle pyruvate kinase kinetics remain unchanged, indicating tissue-specific metabolic adaptation to dehydration stress.
When the frog loses a lot of water, its liver turns on a special switch that makes an energy-making enzyme work better without needing more of it. This enzyme becomes more sensitive to its fuel and a helper molecule, so it keeps producing energy even when the frog's body is slowing down. The muscle does not change this enzyme at all, so only the liver adapts to save energy.
What the research says
1 studyWhen these frogs get super dry, their liver changes its energy-making enzyme to work better, but the same enzyme in their muscles stays the same—so only the liver adapts to save energy.
