Question

based on what you have learned about cellular respiration, select the true statements. an organisms cells rearrange the atoms of energy - rich molecules from food. atoms are neither created nor destroyed during cellular respiration. energy is released during cellular respiration. in cellular respiration, the amount of energy used to break chemical bonds is greater than the amount of energy released by forming new bonds.

Explanation:

• An organism's cells rearrange the atoms of energy - rich molecules from food: Cellular respiration involves the breakdown of energy - rich molecules (like glucose) obtained from food. The atoms in these molecules are rearranged through a series of chemical reactions.
• Atoms are neither created nor destroyed during cellular respiration: This is in line with the law of conservation of mass. In cellular respiration, just like in any chemical reaction, atoms are only rearranged; no new atoms are created, and no atoms are destroyed.
• Energy is released during cellular respiration: The breakdown of energy - rich molecules (such as glucose) in cellular respiration releases energy. This energy is used to produce ATP (adenosine triphosphate), which is the energy currency of the cell.
• In cellular respiration, the amount of energy used to break chemical bonds is greater than the amount of energy released by forming new bonds: This statement is false. In cellular respiration (especially aerobic respiration), the overall process is exergonic. The energy released by forming new bonds (in the products like carbon dioxide and water) is greater than the energy used to break the bonds in the reactants (glucose and oxygen).

Answer:

• An organism's cells rearrange the atoms of energy - rich molecules from food.
• Atoms are neither created nor destroyed during cellular respiration.
• Energy is released during cellular respiration.
