The series of canals used to transport materials throughout the cytoplasm in the cell is Endoplasmic reticulum. It comprises of the rough endoplasmic reticulum, with the ribosomes attached to its surface and the smooth endoplasmic reticulum( no ribosomes attached)
The bond energy is defined as equal to the amount of energy given out when the bond is made (or absorbed when that the bond is broken).
So when a bond is made, and the system cools to its original energy, the amount of energy given out, -DeltaH, is more or less equal to the bond energy.
Noticed that minus sign. For a process that releases heat, DeltaH is negative.
Internet to the rescue
Hope this helps!
