Question

Biological system using energy to carry out endothermic reaction

Answer 1

In exothermic chemical reactions, the heat that is released by the reaction takes the form of electromagnetic energy. ... In contrast, when endothermic reactions occur, energy is absorbed to place an electron in a higher energy state, such that the electron can associate with another atom to form a chemical complex.
