Explanation:
The process of cellular respiration uses sugar and provides energy to cells.
Animals break down sugar through cellular respiration.
Explanation:
An element is a distinct substance that cannot be split-up into simpler substances. Elements are substances made up of a single atom.
Compounds are substances composed of two or more kinds of atoms that are joined together. The properties of a compound are distinct from those of the combining atoms.
When compound breaks down, their atoms are re-arranged and energy is often released.
This is why sugar is a compound capable of releasing energy. It is because it is a compound.
If atoms are broken down, they release nuclear energy in the process. This form of energy is clearly different from that which accompanies the breaking down of a compound.
*****
Sugar dissolving in water does not show that it is a compound. Some elements are also capable of being dissolved in water.
Chemical reactions are not only designed for compounds, elements and molecules are also involved.
