Proton pumpA proton pump is an integral membrane protein pump that builds up a proton gradient across a biological membrane. Proton pumps catalyze the following reaction: H+[on one side of a biological membrane] + energy H+[on the other side of the membrane] Mechanisms are based on energy-induced conformational changes of the protein structure or on the Q cycle. During evolution, proton pumps have arisen independently on multiple occasions. Thus, not only throughout nature but also within single cells, different proton pumps that are evolutionarily unrelated can be found.

Élan vitalÉlan vital (elɑ̃ vital) is a term coined by French philosopher Henri Bergson in his 1907 book Creative Evolution, in which he addresses the question of self-organisation and spontaneous morphogenesis of things in an increasingly complex manner. Élan vital was translated in the English edition as "vital impetus", but is usually translated by his detractors as "vital force". It is a hypothetical explanation for evolution and development of organisms, which Bergson linked closely with consciousness – the intuitive perception of experience and the flow of inner time.
VitalismVitalism is a belief that starts from the premise that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things." Where vitalism explicitly invokes a vital principle, that element is often referred to as the "vital spark", "energy", "élan vital" (coined by vitalist Henri Bergson), "vital force", or "vis vitalis", which some equate with the soul.
