Exemplary Quiz

(Note: Questions in this exemplary quiz were used from a set of questions prepared by Gnaiger Erich for his presentation at MiPschool Tromso-Bergen 2018: The protonmotive force and respiratory control. 1. Coupling of electron transfer reactions to vectorial translocation of protons. 2. From Einstein’s diffusion equation on gradients to Fick’s law on compartments.

(Only one correct answer)

Convert the molar format of the Gibbs force of reaction, ΔkFnO2 [kJ/mol], into the electrical format, ΔkFeO2 [V].

1 Which physicochemical constant is required?

2 What is the meaning of the symbol z_O2?

	Charge number of O2 = 4
	Elementary charge of O2 in [C]
	Atomic number of O2 = 8
	Alphabetical order of O2 isotope

3 How are the units of electric energy [J] and electric force [V] related?

	V = J.F)/C
	V = J.C
	V = J/C.F)
	V = J/C

4 Express -460 kJ/mol O₂ as electrical force in units of volt [V].

	1.2 V
	-1.2 V
	- 1.2 kV
	- 120 V

5 Why should we do that?

	To feel insecure
	To get free drinks
	To express both in identical motive units [MU]
	To compliment our brain mitochondria
