During cellular respiration, the molecule that is primarily broken down is **sugar** (specifically glucose). The breakdown of sugar occurs to release energy, which is then used to convert ADP to ATP. The other molecules listed (carbon dioxide, ADP, and water) are involved in the process but are not the primary molecule being broken down.

During cellular respiration, when pyruvic acid is created (specifically during glycolysis), in addition to the production of four ATP, **heat** is also produced as a byproduct of the reactions. Therefore, the correct response is **heat**.
Answered by GPT-4o mini
The correct response is: **It is less electronegative than oxygen.**

In the context of cellular respiration, hydrogen molecules bond tightly to oxygen due to the significant difference in electronegativity between these two elements. Oxygen is highly electronegative, meaning it has a strong attraction for electrons; thus, it attracts hydrogen, which is less electronegative. This difference in electronegativity leads to the formation of covalent bonds and the strong interactions in molecules like water.
