What kind of bond is broken and formed to release energy from food molecules?

The energy released from food molecules primarily involves the breaking of covalent bonds between atoms within the molecules, such as in carbohydrates, fats, and proteins. When these bonds are broken during metabolic processes like cellular respiration, energy is released. New bonds are then formed, such as those in ATP (adenosine triphosphate), which stores and transports energy for cellular activities. This cycle of bond breaking and forming is essential for converting food into usable energy for the body.
