Source of entropy decrease in biosystems

  • Published:
Il Nuovo Cimento D

Summary

Entropy changes are evaluated for all possible coupled reactions which define the overall biochemical processes. Predictions are well supported by all known data. The results show that biochemical process in animal systems yield a net decrease of entropy thanks to respiration. It is shown also that the respiration is the primary source of entropy decrease in vegetal systems.

Riassunto

Si valutano le variazioni di entropia per tutte le possibili reazioni accoppiate che definiscono l'intera sequenza di un completo processo biochimico. I valori previsti sono in buon accordo con tutti i dati da noi conosciuti. I risultati mostrano che i processi biochimici inducono una diminuzione netta di entropia all'interno dei sistemi animali grazie al processo di respirazione. Si mostra inoltre che anche nei sistemi vegetali la variazione negativa di entropia è prevalentemente determinata dal processo di respirazione.

Резюме

Оцениваются изменения энтропии для всех возможных связанных реакций, которые полностью определяют биохимические поцессы. Предсказания хорощо согласуются со всеми известными данными. Полученные результаты покзывают, что биохимические процессы в животных системах приводят к результирующему уменьшению энтропии вследствие дыхания. Показывается, что дыхание представляет первичный источник уменьшения энтропии также в растительных системах.
