pH and Buffers

pH is a measure of the acidity or alkalinity of a solution, quantified on a scale from 0 to 14, where values below 7 indicate acidity, 7 is neutral, and above 7 indicates alkalinity. Buffers are chemical systems that help maintain a stable pH in biological systems by neutralizing excess acids or bases, thereby ensuring optimal conditions for enzymatic and metabolic processes.

Overview

pH and buffers play a vital role in biological systems by maintaining the appropriate acidity or basicity necessary for life. The pH scale ranges from 0 to 14, with 7 being neutral. Biological processes, including enzyme activity and metabolic reactions, are highly sensitive to pH changes. Buffers, ...

Key Terms

pH
A scale used to specify the acidity or basicity of an aqueous solution.

Example: A pH of 7 is neutral, below 7 is acidic, and above 7 is basic.

Buffer
A solution that resists changes in pH when small amounts of acid or base are added.

Example: The bicarbonate buffer system in blood helps maintain pH.

Acid
A substance that donates protons (H+) in a solution.

Example: Hydrochloric acid (HCl) is a strong acid.

Base
A substance that accepts protons or donates hydroxide ions (OH-) in a solution.

Example: Sodium hydroxide (NaOH) is a strong base.

Homeostasis
The process by which biological systems maintain stability while adjusting to conditions.

Example: The body regulates temperature and pH to maintain homeostasis.

Enzyme
A protein that acts as a catalyst to speed up biochemical reactions.

Example: Amylase is an enzyme that helps digest carbohydrates.
