Princippet for endoterm energilagringsteknologi

Eksoterm, om en kemisk eller fysisk proces (reaktion), som medfører frigørelse af energi. Langt de fleste kemiske reaktioner forløber med frigørelse eller absorption af energi. For en eksoterm reaktion omsættes den frigjorte energi til termisk energi (varme) af reaktionsprodukterne eller disses omgivelser.

What are ectothermy and endothermy?

Ectothermy and endothermy constitute the major thermoregulatory strategies in living organisms. While ectotherms can be prone to changes in body temperature (T b) in correlation with ambient temperature (T a) variations, the internal physiological milieu of endotherms remains relatively stable despite acute external thermal fluctuations.

What is an endothermic reaction?

In an endothermic process, the heat that a system absorbs is thermal energy transfer into the system. Thus, an endothermic reaction generally leads to an increase in the temperature of the system and a decrease in that of the surroundings. The term was coined by 19th-century French chemist Marcellin Berthelot.

How do endotherms regulate their body temperature?

Endotherms regulate their body temperature by varying their insulation seasonally and depending on climate. Above the TNZ, endotherms lose heat by evaporation of water. Endothermy evolved independently in mammals and birds, but the precise timing of its evolution is not clear in either lineage.

What is an endotherm animal?

An endotherm is an animal that generates and controls its internal heat so that its body core temperature can be regulated at a level different than the ambient temperature. You might find these chapters and articles relevant to this topic. M.K. Labocha, J.P. Hayes, in Encyclopedia of Ecology, 2008 Which Organisms Are Endotherms?

What is endothermy in biology?

1. Introduction Endothermy, i.e. the ability for an organism to generate body heat through a specifically dedicated metabolic activity, is considered to have appeared at least twice in the evolution of vertebrates, in the mammalian and avian lineages [1, 2].

What is the difference between thermoregulation and endotherm?

In biology, thermoregulation is the ability of an organism to maintain its body temperature, and the term "endotherm" refers to an organism that can do so from "within" by using the heat released by its internal bodily functions (vs. an "ectotherm", which relies on external, environmental heat sources) to maintain an adequate temperature.

An endothermic process is a chemical or physical process that absorbs heat from its surroundings. In terms of thermodynamics and thermochemistry, it is a thermodynamic process with an increase in the enthalpy H (or internal energy U) of the system. In an endothermic process, the heat that a system absorbs is thermal energy transfer into the system. Thus, an endothermic reaction generally leads to an increase in the temperature of the system and a decrease in that o…
