Cofactors and Coenzymes exist to help molecules bind to enzymes. It is temporary through ionic or hydrogen bonds and permanent through covalent bonds.
Cofactors are inorganic ions, ie: iron and magnesium.

ATP in coupled reactions
Cells couple the ATP hydrolysis' exergonic reaction allowing them to proceed. One example of energy coupling using ATP involves a transmembrane ion pump that is extremely important for cellular function.
Essentially, the energy released from the ATP hydrolysis couples with the energy required to power the pump and transport Na+ and K+ ions. ATP performs cellular work using this basic form of energy coupling through phosphorylation.
Cells use ATP to perform work by coupling ATP hydrolysis' exergonic reaction with endergonic reactions.

Many chemical reactions required activation energy to occur. The activation energy determines the rate @ which the reaction will proceed. The higher the activation energy, the slower the reaction occurs.
This can be lowered by enzymatic-substrate complex that contorts substrate molecules to facilitate bond-breaking.
