First edition (publ. Doubleday) Life and Energy is a 1962 book by Isaac Asimov.It is about the biological and physical world, and their contrasts and comparisons.Thus the book is divided into two sections, which is separated by further sub-sections (i.e. chapters): 1) energy; 2) body.
Like the Earth as a whole, living things use this energy, converting the energy to other forms (the first law), while producing entropy (the second law), and thereby degrading the exergy or quality of the energy. Sustaining life, or the growth of a seed, for example, requires continual arranging of atoms and molecules into elaborate assemblies ...
Energy (from Ancient Greek ... Basic overview of energy and human life. In biology, energy is an attribute of all biological systems, from the biosphere to the ...
If a system has a definite temperature, then its total energy has three distinguishable components, termed kinetic energy (energy due to the motion of the system as a whole), potential energy (energy resulting from an externally imposed force field), and internal energy. The establishment of the concept of internal energy distinguishes the ...
Definition of cellular life according to Budisa, Kubyshkin and Schmidt. Budisa, Kubyshkin and Schmidt defined cellular life as an organizational unit resting on four pillars/cornerstones: (i) energy, (ii) metabolism, (iii) information and (iv) form.
Biological thermodynamics (Thermodynamics of biological systems) is a science that explains the nature and general laws of thermodynamic processes occurring in living organisms as nonequilibrium thermodynamic systems that convert the energy of the Sun and food into other types of energy. The nonequilibrium thermodynamic state of living ...
Because living systems involve net movement in terms of chemical movement or body movement, and lose energy in those movements through entropy, energy is required for a living system to exist. The main source of energy on Earth is the sun, but other sources of energy exist for life on Earth, such as hydrogen gas or methane, used in chemosynthesis.
Energy (esotericism), a term used by various esoteric forms of spirituality and alternative medicine Prana, the Sanskrit word for "life force" or "vital principle" Qi, a vital force in traditional Chinese philosophy; Élan vital, a hypothetical explanation for evolution and development of organisms
