Abstract Cells are open systems that exchange energy and molecules with their environment. As any material system,
they perform all the complex activities required for homeostasis and reproduction, obeying the thermodynamic laws.
This viewpoint will argue that the basic logic governing the energy flux required to preserve cell organization and
function is simple: to decrease the activation energy (Ea) of specific processes. Almost none of the possible chemical
reactions and energy transformations inside a cell occur at a measurable speed at room or body temperature.
Enzymes or other macromolecular structures speed up particular transformations by decreasing the corresponding
energetic barriers. However,… More >
