Question

consider the data table given. at what ph does this enzyme have the lowest activity? explain why, what happened to the enzyme?

Explanation:

Enzymes are proteins, and their activity is affected by pH. Extreme pH values (either too acidic or too basic) can denature enzymes. Denaturation changes the enzyme's 3 - D structure (especially the active site), preventing it from binding to substrates effectively. Looking at the data, the lowest enzyme activity (1 unit/min) occurs at pH = 1, which is a very acidic condition.

Answer:

The enzyme has the lowest activity at pH = 1. At this pH, the enzyme is denatured. Denaturation disrupts the enzyme's structure (such as hydrogen bonds, ionic bonds in its protein structure), altering the active site so that it can no longer bind substrates efficiently to catalyze reactions.
