Because the proteins that help to maintain molecular fidelity are also subject to the second law of thermodynamics,the ability to repair or replace damaged biomolecules also decreases with age.

Question

Quizplus · Accepted Answer

This statement is true because the second law of thermodynamics states that entropy (disorder) in a system increases over time, including in biological systems. As a result, the proteins that help to maintain molecular fidelity, such as chaperones and enzymes, are also subject to this increase in entropy and their ability to repair or replace damaged biomolecules decreases with age.
