Item EB022002: The process by which organisms obtain energy from food involves a chemical reaction between oxygen and carbon-containing molecules from food. During the reaction, atoms are rearranged to form different molecules, and energy is released as the bonds of these new molecules form.

Which of the following statements is TRUE about the process by which organisms obtain energy from food for life’s processes?

  1. The process of obtaining energy involves a chemical reaction that breaks down carbon-containing molecules from food and turns the atoms into energy.
  2. The process of obtaining energy involves a chemical reaction that breaks the bonds between the atoms of the carbon-containing molecules from food. Energy is released when the bonds between atoms break.
  3. The process of obtaining energy involves a chemical reaction between oxygen and carbon-containing molecules from food. During the reaction, atoms are rearranged to form different molecules, and energy is released as the bonds of these new molecules form.
  4. The process of obtaining energy does not involve a chemical reaction. Food is energy, so nothing else has to be done to the food to get energy from it.
