Organisms need to obtain energy via cellular respiration in order to break down molecules, such as glucose, and convert them into usable energy in the form of ATP (adenosine triphosphate). This energy is essential for various cellular processes, including growth, reproduction, and the performance of metabolic activities. While photosynthesis is a process that produces glucose, organisms themselves cannot directly carry out photosynthesis. Therefore, they rely on cellular respiration to obtain energy from the glucose produced by plants. Additionally, glycolysis is a part of cellular respiration where glucose is partially broken down, but it is not the only step. Cellular respiration involves multiple steps, including glycolysis, the citric acid cycle, and oxidative phosphorylation, all of which work together to produce ATP.
