Understand the Problem
The question is asking about a specific component that is vital for maintaining proper pH levels in biological systems. The focus is on identifying which of the provided options serves that purpose.
Answer
Buffers.
The final answer is buffers.
Answer for screen readers
The final answer is buffers.
More Information
Buffers are solutions that resist changes in pH. They moderate pH fluctuations in biological systems by absorbing excess hydrogen ions when pH levels drop and donating hydrogen ions when pH levels rise.
Tips
A common mistake is to overlook the specific role of buffers, thinking they completely prevent pH changes rather than resisting them. Understanding that they stabilize rather than eliminate pH changes is crucial.
