Answer:
(B) The concentration of ATP in cells is generally much lower than that of AMP.
Explanation:
AMP is 5’-adenylic acid or adenosine monophosphate. It has only one phosphate group attached to the sugar as compared to three phosphate groups of ATP. In general, cells have a much lower concentration of AMP than ATP. ATP is found in much higher concentration in cells than the AMP since ATP serves as energy currency for the cells while AMP is involved in relatively few metabolic pathways.
