Final answer:
Protein function is primarily dependent on its shape. Changes in temperature, pH, and exposure to chemicals can cause a protein to lose its shape, leading to a loss of function or denaturation.
Step-by-step explanation:
Protein function is primarily dependent on its shape. Proteins have different shapes, such as globular or fibrous, and these shapes are critical for their proper functioning. Changes in temperature, pH, and exposure to chemicals can cause a protein to lose its shape, leading to a loss of function or denaturation.
