The correct answer is b. by cellular respiration. ATP (adenosine triphosphate) is produced through the process of cellular respiration, specifically during the electron transport chain in the mitochondria of cells. This process involves the oxidation of glucose and other molecules to release energy, which is then used to generate ATP. Ribosomes are responsible for protein synthesis, while protein synthesis is a cellular process that involves the creation of proteins based on the instructions encoded in DNA. Easy bake ovens have no role in ATP production or any cellular processes in living organisms.
