Effect of temperature on enzymatic activity

Thermodynamics is the study of a system as it evolves based on mechanical and thermal exchanges with the external environment.

 H: (Enthalpy): Enthalpy is a state function expressed in Joules (J). The term originates from Greek and refers to the heat. It represents the internal heat contained in a molecule.

 ΔH (Enthalpy Change) or change in enthalpy, which represents the heat variation between the system where the reaction takes place (the studied part) and the surrounding environment (the remaining part).
