Final answer:
Peripheral membrane proteins can be removed from the membrane by changing the pH of the environment. Extreme pH levels can disrupt the protein's structure and function.
Step-by-step explanation:
Peripheral membrane proteins are proteins that are temporarily associated with the membrane. They can be easily removed from the membrane. This removal can be achieved by changing the pH of the environment. Extreme pH levels can disrupt the hydrogen bonds that hold the protein in place, causing it to lose its three-dimensional conformation and function. When the pH is altered away from the optimum for a specific protein, it can severely hamper its function throughout the body.
