Frage 1

Frage
What is the difference between Stage 3 & Stage 4?
Antworten
  • Stage 3 is between ADP addition and ADP running out
  • Stage 3 is between ADP running out and oxygen running out
  • Stage 4 is between ADP running out and oxygen running out
  • Stage 4 is between O2 running out and ADP running out

Frage 2

Frage
Measuring oxygen consumption is done by looking at the change in the X co-ordinates
Antworten
  • True
  • False

Frage 3

Frage
Once you've worked out the change in O2 concentraction, how do you calculate nmol O2 /min/mg protein
Antworten
  • Divide by mg of protein
  • Divide by 60
  • Divide by O2 consumed

Frage 4

Frage
Assume a change in the axis of 15mm, and a protein concentration of 1.4mg. Calculate the Rate
Antworten
  • 25.7 nm Oxygen/min/mg protein
  • 10.7 nm Oxygen/min/mg protein
  • 50.4 nm Oxygen/min/mg protein

Frage 5

Frage
What is the equation for the respiratory control ratio?
Antworten
  • Rate of phase 4/ Rate of phase 3
  • Rate of phase 3/ Rate of phase 4
  • Rate of phase 3 x Rate of phase 4

Frage 6

Frage
ADP/O ratio = Moles of ADP added/Moles of ADP consumed
Antworten
  • True
  • False

Frage 7

Frage
To convert from O2 to O, what must you do?
Antworten
  • Double it
  • Halve it
  • Square it

Frage 8

Frage
What must be checked before calculating the ADP/O ratio?
Antworten
  • That both sides are in the same molar concentration
  • That the oxygen consumed has been converted into nm
  • That the ratio is positive
