Oxidation Practical

Question 1 of 8

1

What is the difference between Stage 3 & Stage 4?

Select one or more of the following:

  • 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

Explanation

Question 2 of 8

1

Select one of the following:

  • True
  • False

Explanation

Question 3 of 8

Select one of the following:

  • Divide by mg of protein

  • Divide by 60

  • Divide by O2 consumed

Explanation

Select one of the following:

  • Double it

  • Halve it

  • Square it

Explanation

Question 8 of 8

1

What must be checked before calculating the ADP/O ratio?

Select one of the following:

  • That both sides are in the same molar concentration

  • That the oxygen consumed has been converted into nm

  • That the ratio is positive
