Question

describe how temperature affects enzyme activity and explain what happens to an enzyme if the temperature is too high. enter your answer in the box provided.

Explanation:

Enzymes are proteins. As temperature increases from low levels, enzyme - substrate collisions increase, enhancing activity up to an optimal temperature. Beyond the optimal temperature, high heat disrupts the enzyme's 3 - D structure (denaturation), breaking hydrogen bonds and other interactions that maintain its shape. This changes the active - site conformation, reducing or eliminating its ability to bind to the substrate.

Answer:

As temperature increases from low values, enzyme activity increases due to more frequent enzyme - substrate collisions until reaching the optimal temperature. When the temperature is too high, the enzyme denatures. Its 3 - D structure is disrupted, the active - site shape changes, and it can no longer effectively bind to the substrate, leading to a significant decrease or complete loss of enzyme activity.
