amino acid

|
|
polypeptide

|
|
phospolipid

chemical bond

Explanation:
Detailed explanation-1: -It takes energy to break bonds. Energy is released when bonds are formed.
Detailed explanation-2: -Energy is absorbed to break bonds, and energy is evolved as bonds are made. In some reactions the energy required to break bonds is larger than the energy evolved in making new bonds, and the net result is the absorption of energy.
Detailed explanation-3: -When the bond is broken, energy is released. The type of energy that breaks the bonds can be light, heat, or kinetic.
Detailed explanation-4: -The bottom line is that both endothermic and exothermic reactions involve the breaking of bonds, and both therefore require energy to get started. It makes sense that breaking bonds always takes energy.
