Answer:
The correct answer is "the production of ATP." Cellular respiration is the process by which cells break down glucose and other organic molecules to produce ATP (adenosine triphosphate), which is the energy currency of the cell. It is through cellular respiration that cells obtain the necessary energy to carry out their functions. The other options mentioned, such as cellular reproduction, tissue creation, and passive transport mechanisms, are not directly related to the primary focus of cellular respiration.
