Step-by-step explanation:
1. The daily food consumption of an organism provides fuel and building blocks for the body.
2. Food is broken down via the digestive system
3. With the assistance of the circulatory system, the digestive system supplies nutrients and water to the cells.
4. Within a cell, fuel molecules are further broken down during the following steps: glycolysis, the prep reaction, and the citric acid cycle.
5. Large quantities of ATP are produced when electron carriers travel to the electron transport chain embedded in the inner membrane of the mitochondria.
