ATP Is the Molecule Most Often Used for Energy Transport

ATP is the molecule most often used for energy transport because

A) a relatively large amount of energy is released upon hydrolysis of its two phosphoric anhydride bonds.
B) its hydrolysis releases an intermediate amount of energy and is relatively slow except in the presence of the appropriate enzymes.
C) it can only be produced in the citric acid cycle.
D) it can only be produced as a result of reactions in the electron transport chain.
E) its production from ADP is endergonic.
