The process that is not part of the cellular respiration pathway that produces large amounts of ATP in a cell is photosynthesis.

Here's why:

* Cellular respiration is the process by which cells break down glucose (sugar) in the presence of oxygen to produce energy in the form of ATP. It has four main stages: glycolysis, the link reaction, the Krebs cycle, and oxidative phosphorylation.

* Photosynthesis is the process by which plants and some other organisms use sunlight to synthesize foods with high chemical energy, primarily sugars, from carbon dioxide and water. This process actually creates glucose, which is the fuel cellular respiration uses to produce ATP.
