Which explains how buffers cells to maintain homeostasis

Keep pH within the cell constant.

Explanation:

Buffers help cells maintain homeostasis because they allow pH balance, allowing the pH within the cell to remain constant.

A buffer is a substance that does not undergo pH variation and can pass this characteristic on to the system that is housing it, such as a cell, for example. Buffer also does not allow the alteration of pOH, which is extremely important for a cell to be able to maintain its dynamic balance.
