Definition

An 'endergonic' reaction is a chemical reaction that requires energy to be absorbed from the surroundings. Think of it like charging your phone πŸ”‹; you need to put energy in. The products of the reaction have more energy than the reactants. It's like an uphill process that requires energy input. It’s the opposite of exergonic and won't happen without that energy.

Etymology

The word 'endergonic' is derived from the Greek prefix 'endo-' meaning 'in' or 'inside', and 'ergon' meaning 'work' or 'energy'. This combination describes a process where energy enters the system. The term was coined in the 20th century to describe chemical reactions that require free energy input.
