If glucagon did not activate glycogenolysis the water potential of the blood would fall too low


Wouldn't the water potential of blood be too high?

Yes, you're right, the water potential of the blood would be too high, as glucose levels would be low; low solute concentration = high water potential.

I don't understand why exam boards insist on using "water potential" - it is counterintuitive and would be so much easier to use osmolality. Osmolality is a measurement of solute concentration, the higher the solute concentration (e.g. glucose), the higher the osmolality.
