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, Ξ”kFnO2 [kJ/mol], into the electrical format, Ξ”kFeO2 [V].

1 Which physicochemical constant is required?

2 What is the meaning of the symbol zO2?

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

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

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

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

- 1.2 kV
-1.2 V
- 120 V
1.2 V

5 Why should we do that?

identical motive units [MU]
To feel insecure
To compliment brain mitochondria
To get free drinks
