How does lipids use as energy? 

• By eating fats

• By storing fats

• By collecting fats

• By burning of  fats

Explain why energy store in fats is more important than the energy store by carbohydrates in the form of glycogen?

• Energy store in fats is more easy to use than the carbohydrates

• Energy in fats produces more energy that the quick energy given by glycogen.

• Energy in fats is needed more effort to breakdown and short time to use than the glycogen.

• Fats and glycogen are same important role in energy storing.

Explain the process of Hydrogenation.

• The double chain fatty acid  that unable to accept hydrogen.

• The capacity of unsaturated fatty acid to accept hydrogen as a result of saturated fatty acid

• A hydrogen is introduce to saturated fatty acid to be able to produce more saturated fatty acid
