Lipids serve as structural components of cell membranes, function as energy storehouses, and function as important signalling molecules. They include fats, waxes, oils, hormones, and certain components of membranes and function as energy-storage molecules and chemical messengers.
Hope this helped :)
The first law of thermodynamics states the conservation of energy and heat where the <span>total energy in an isolated system may be transformed into another, but never created or destroyed. If 314 J of energy was released to the room, then also 314 J of energy was also removed from food in that refrigerator assuming it is an isolated system. </span>

You start at He and work you way down
The enthalpy change, ΔH for the following reaction 
is -452.76 kJ.
<h3>What is enthalpy change, ΔH, of a reaction?</h3>
The enthalpy change of a reaction is the heat changes that occurs when a reaction proceeds to formation of products.
- Enthalpy change, ΔH = ΔH of products - ΔH of reactants
The equation of the reaction is given below
Therefore, the enthalpy change, ΔH for the following reaction is -452.76 kJ.
