Question

question 5 of 10
this chemical equation summarizes what happens during cellular respiration.
c₆h₁₂o₆ (sugar) + o₂ (oxygen) → thermal energy + h₂o (water) + co₂ (carbon dioxide)
how does the equation best support the idea that, as matter flows between systems, elements are recombined in different ways?
a. each side of the arrow includes two different types of matter.
b. it shows that sugar and oxygen contain the same types of atoms as water and carbon dioxide.
c. thermal energy appears on the same side as sugar and oxygen.
d. the arrow appears between oxygen and thermal energy.

Explanation:

In cellular respiration, the reactants (sugar and oxygen) are composed of carbon, hydrogen, and oxygen atoms. The products (water and carbon - dioxide) also contain carbon, hydrogen, and oxygen atoms, just recombined in different molecules. This shows that as matter flows between systems, elements are recombined.

Answer:

B. It shows that sugar and oxygen contain the same types of atoms as water and carbon dioxide.
