Operational definition
Allocation function.
The conversion of biological free energy into force, displacement, pressure, flow, deformation, or rotation.
It includes:
- muscle contraction;
- flagellar rotation;
- ciliary beating;
- intracellular transport;
- crawling;
- swimming;
- flight;
- migration;
- pumping;
- construction movements.
Mechanical work ultimately produces heat, but it is classified here by its immediate biological function.
