Answer:
Burning sugar results in a chemical reaction
Explanation:
Flammability, odor, and density are just a few examples of characteristic properties of a substance. A chemical reaction occurs when molecules interact with one another and the molecules change. For example burning sugar results in a chemical reaction because the properties of cube B changed when it was burned. This change in solubility shows that cube B must be a different substance than cube A because of the chemical reaction that occurred when cube B was burned.
During aerobic respiration, complete oxidation of carbohydrates takes place. Glucose is broken down by oxygen to release energy, while carbon dioxide and water are the by-products of the reaction. The released energy is used to make a special energy molecule called Adenosine triphosphate (ATP).
This is an indispensable process that allows cells to divide for a living organism to grow or reproduce each new cell needs DNA copy which serves as instructions on how to function as a cell.
