Do you feel the Coupling?

Note: This quiz was made to test your knowledge of mitochondrial terminology of coupling states and to help you understand basic concepts of mitochondrial physiology


1 Maximal oxygen flux JkO2 is reached in:

state.

2 LEAK state can be measured:

In the absence of ADP
After uncoupler titration
In the absence of substrates
After addition of kinetically saturation doses of ADP

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

V = J/C
V = JยทC
V = (JยทF)/C
V = J/(CยทF)

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

- 120 V
- 1.2 kV
1.2 V
-1.2 V

5 Why should we do that?

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