Under steady-state conditions in a mammalian cell,the adenine nucleotide concentrations are [ATP] = 3.3 mM,[ADP] = 1.2 mM,and [AMP] = 0.2 mM.What is the energy charge of this cell?
A) 0.83
B) 0.95
C) 0.72
D) 1.2

Question

Quizplus · Accepted Answer

The energy charge is calculated using the formula: ( [ATP] + 0.5[ADP] ) / ( [ATP] + [ADP] + [AMP] ). Substituting the given values: (3.3 + 0.5*1.2) / (3.3 + 1.2 + 0.2) = 0.83.
