water potential (Ψ)
measure of the potential energy in water to flow from an area of HIGH water potential to LOW water potential
ionization constant (i)
the number of particles a solute dissociates into in water (total number of ions produced, or 1 for covalent compounds like sucrose and glucose) (Ψ)
What is the ionization constant for ions?
total number of ions produced
What is the ionization constant for covalent compounds like sucrose and glucose?
one
pressure constant (R)
0.0831 [L*bars / mol*K]
What is the pressure constant of an open container?
0.0831 (so just multiply by that)
What does adding solute do to water potential?
it lowers it, as water is less likely to leave the solution and makes the solution more concentrated
What does a more negative solute potential mean?
more solute molecules are present
What does a high water potential mean?
a high concentration of water (low solute)
Q10
measure of temperature sensitivity of a physiological process or enzymatic reaction rate: Q10 = (k2 / k1)^10/T2-T1
Q10: T1 and T2
temperature unit (make sure you are using the same one)
Q10: k1 and k2
reaction rates
Q10: Q10
no unit, factor by which the rate of a reaction increases due to a temperature increase
high Q10
more temperature dependent reaction
Q10 of 1
the reactions are temperature independent
