Answer: no

Explanation:

Cellular respiration is the process through which our cells get the energy to perform their functions.

During aerobic respiration, oxygen is present, and this results in a larger amount of energy. Even though anaerobic cellular respiration lacks the presence of oxygen, it is still able to produce energy, just smaller amounts of it. This process is called fermentation.

During cellular respiration, food molecules are broken down from sugar molecules to energy molecules known as ATP. ATP is also considered to be the 'energy currency' of cells. ATP stores energy in a strong bond, and cells can harness this energy by breaking that bond, thereby removing a phosphate group and resulting in ADP, which can then be reconverted to ATP. At the end of anaerobic respiration, there are only two molecules of ATP produced. During aerobic cellular respiration, there are a maximum of 38 molecules of ATP formed.
