Answer: Option D

Explanation:

The early earth conditions were different from the conditions that exists today. Too much of oxygen in the atmosphere hinders the formation of cells.

Many experiments were performed to form organic compounds but none of them helped to form cells.

This is because after the formation of organic molecule, it took time for the formation of cells. There is no such experiment that can be performed for such a longer duration of time, so cells cannot be formed.

During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes.
UkoKoshka [18]

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

Explanation:

The correct statement from the given choices is that new compounds with lower-energy bonds must be formed when the high- energy bonds in the food molecules are broken down.

Cellular respiration is classified as an catabolic  process in which an energy rich substance is broken down into a lesser one.

  • Metabolic processes are usually divided into catabolic and anabolic processes.
  • In catabolic step, energy is broken down.
  • Cellular respiration is catabolic whereas photosynthesis is anabolic.
  • The new compounds formed have lower energy bonds after respiration.
