The correct answer is: to break down ATP.
The correct answer is "to break down ATP."
Organisms need to obtain energy through cellular respiration in order to break down ATP (adenosine triphosphate). ATP is the primary energy currency of cells, and it provides the necessary energy for various biological processes such as muscle contraction, active transport, and synthesis of molecules.
To find this answer, you could have eliminated the options that are not directly related to the production or breakdown of ATP.
Option 1, "to photosynthesize," is incorrect because photosynthesis is a process by which plants and some other organisms convert light energy into chemical energy (in the form of glucose) and not the breakdown of ATP.
Option 3, "to perform glycolysis," is also incorrect because glycolysis is the initial step in cellular respiration, where glucose is partially broken down to produce ATP. However, glycolysis alone is not sufficient to provide all the energy needed by organisms.
Option 4, "to grow and reproduce," is also not the correct answer because while cellular respiration does provide the energy for growth and reproduction, it is not the primary reason organisms need to obtain energy through cellular respiration.
To summarize, organisms obtain energy through cellular respiration primarily to break down ATP, which is essential for various cellular processes.
