1. Cellular work: This includes all the processes that keep a cell alive and functioning. Examples include:
* Muscle contraction: Moving your body.
* Active transport: Moving molecules across cell membranes.
* Synthesis of new molecules: Building proteins, fats, and carbohydrates.
* Cell signaling: Communicating between cells.
* Maintaining cell structure: Keeping the cell organized.
2. Heat production: Not all energy is used for cellular work. Some is released as heat, which helps maintain body temperature in warm-blooded animals.
Essentially, the energy released from breaking down molecules is used to power the cell's activities and to maintain a stable internal temperature.
