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
