We burn Lipids, Carbohydrates and Proteins. The 'Particular Order' depends upon 'Substance Availability'.
Chemical energy that is contained in and transported by the molecule called Adenosine Tri Phosphate.
ATP
Glucose and triglycerides
fat, calories, sugar, and energy or glucose
How about: 'Energy sources are essential for an industrial economy'
Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.
For the most part, oxygen is used to help cells generate energy from carbon sources. Some cells can use oxygen to generate toxins which are used to kill pathogens.
non conventional energy sources are those energy sources which are exposed to use from modern technologies advancements ; rather than the normal use of conventional fuels as energy sources like gas or oil
Alternative energy
Cells have multiple sources of nutrients including fats and sugars, that can be used to create energy. As far as sugar is concerned, glucose is the sugar that is used by cells to produce energy.
Cells use carbohydrates as a source of energy and for energy storage.
Lipids are used for energy storage, cushions vital organs, and insulates the organism
