Bond Broken and Forming

Are these two theories in conflict?

a) When large molecules are broken down (ie. catabolic), energy is RELEASED. When small molecules build up into big ones (anabolic), energy is REQUIRED.

b) According to the Bond dissocation Equation, the enthalpy of bonds broken is endothermic (REQUIRE energy) and that of bonds forming is exothermic (RELEASE energy)

Thanks!
