Denoting a chemical reaction in which the products contain more energy than the reactants, so energy is stored in the reaction. Energy must be put into such a reaction to make it go.
A chemical reaction requiring input of energy to proceed.
nonspontaneous reaction that proceeds with the absorption of free energy; work must be done to make the reaction proceed. (see exergonic)
An energy-requiring reaction.
A process that leads to an increase in the free energy of a system and is therefore not spontaneous.
Chemical reactions that require energy input to begin.
Endergonic means to absorb energy in the form of work. Its etymology stems from the suffix -ergonic as derived from the Greek root ergon meaning to work, combined with the prefix end- as derived from the Greek root en meaning put into. By thermodynamic standards, work, a form of energy, is defined normally to move from the surroundings (the external region) to the system (the internal region).
