pH and Enzyme Activity

pH has a crucial impact on enzyme activity:

• Each enzyme has an optimum pH range where it functions most efficiently
• Extreme pH levels can denature enzymes, causing them to lose their catalytic activity
• Changes in pH can alter the ionic bonds and hydrogen bonds in the enzyme, affecting its shape and function

For example, pepsin in the stomach works best at a low pH (acidic environment), while trypsin in the small intestine functions optimally at a slightly alkaline pH.
