Question

During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes. In order for this to occur, which of the following statements must be true?
A.) The energy in the new compounds that are formed must be equal to the energy in the bonds of the food molecules.

B.) New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.

C.) New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken.

D.) The new compounds that are formed must be more complex than the food molecules that were broken down.

Answer 1

During cellular respiration, the bonds of food molecules are broken to energy can be released to fuel other cellular processes. In order for this to occur, new compounds with lower-energy bonds must be formed when high-energy bonds in food molecules are broken.
This is due to the Law of Conservation of Energy. 

Answer 2

Answer:

The correct answer is statement B.

Explanation:

The cellular procedures of respiration and photosynthesis involve the transformation of energy and matter. On the basis of the law of conservation of energy, energy can neither be formed nor destroyed. Thus, to attain excess energy in order to provide energy for the cellular procedures, the bonds produced in the new compounds must possess less energy in comparison to the bonds in the original food molecules.
