We often say that we need food for energy. In a biological sense, is this correct?
A) Yes, because the smallest units inside the atoms that make up the food are simply pure energy.
B) Yes, because the food must move through the digestive system, and motion is kinetic energy.
C) Yes, because the food we eat has potential energy in its structure and this chemical energy can be converted into mechanical energy.
D) No, because food consists of matter and cannot be transformed into energy.
E) No, since all food matter stays matter, and energy remains energy.
Potential Energy
The energy stored in an object or system due to its position, condition, or composition, available to do work when its state changes.
Kinetic Energy
The energy possessed by an object due to its motion, which is defined by mass and velocity.
Chemical Energy
Energy associated with the interaction of atoms in a molecule.
- Absorb the basic understanding of energy mechanisms in biological entities, including the rules of thermodynamics.
- Recognize the role of ATP as the energy currency in cells and its various uses.
