Biological Buffers
Biological buffers are substances in living organisms that help maintain stable pH levels in bodily fluids. pH is a measure of how acidic or basic something is, and it's crucial for many biological processes. Buffers work by neutralizing excess acids or bases, ensuring that conditions remain optimal for enzymes and other molecules that support life. For example, bicarbonate in our blood acts as a buffer, preventing drastic changes in pH that could disrupt our body's functions. Essentially, buffers play a vital role in keeping our internal environment balanced and functioning properly.

Biological buffers are substances in living organisms that help maintain a stable pH level in fluids, such as blood. pH is a measure of how acidic or basic a solution is, and many biological processes depend on keeping this balance. Buffers work by quickly absorbing excess hydrogen ions (which make a solution more acidic) or releasing them when they are too few. By doing so, buffers prevent drastic changes in pH that could harm cells and disrupt vital functions. Examples include bicarbonate in blood and phosphate in cells. Thus, biological buffers are essential for overall health and stability in life.
