How nature forces events that shouldn't happen on their own
In short: Why do complex biological systems function if they defy natural entropy? This video explains the mechanisms used to drive nonspontaneous processes through external energy and chemical coupling.
Nature often performs tasks that are energetically unfavorable, known as nonspontaneous processes. To achieve these, systems must overcome thermodynamic barriers using two primary methods: the input of external energy or the clever use of 'coupling.'
Paul Andersen explores how electricity and light serve as external drivers to power reactions. Alternatively, biological systems often couple a nonspontaneous reaction with a spontaneous one—such as the conversion of ATP to ADP—to ensure the overall process proceeds forward.
