Cellular respiration uses one glucose molecule to produce a total of 36 ATPs.
Cellular respiration is the process by which cells generate energy from glucose and other organic molecules. When glucose is fully metabolized through this process, a total of 36 ATP molecules are produced.
To arrive at this answer, it is important to understand the stages of cellular respiration and the number of ATP molecules produced at each step.
1. Glycolysis: This is the initial stage of cellular respiration and occurs in the cytoplasm of the cell. During glycolysis, one molecule of glucose is converted into two molecules of pyruvate. A net gain of two ATP molecules is produced in this step.
2. Pyruvate Decarboxylation: After glycolysis, pyruvate molecules move into the mitochondria and undergo further processing. Each pyruvate molecule is converted into acetyl-CoA in this step, and no ATP molecules are directly produced.
3. Citric Acid Cycle (Krebs Cycle): Acetyl-CoA enters the citric acid cycle, which takes place within the mitochondria. In each cycle, two ATP molecules are produced, but since two cycles occur per glucose molecule, a total of four ATP molecules are generated.
4. Electron Transport Chain (ETC): The ETC is the final step of cellular respiration, taking place in the inner mitochondrial membrane. The NADH and FADH2 molecules generated from the previous steps release their electrons, which are then used to create a gradient for ATP synthesis. The exact number of ATP molecules produced during the electron transport chain can vary, but on average, approximately 32-34 ATP molecules are generated.
Considering the ATP production in all the steps, the total ATP production from one glucose molecule is approximately 36 ATP molecules.
