Question

1. using graph 3, explain how ph affects enzyme activity. relate to temperature effects.

Explanation:

Enzymes have an optimal pH (like pH 7 here) where activity is highest, similar to optimal temperature. Deviations (lower or higher pH) reduce activity as they disrupt enzyme structure (denaturation), just as extreme temperatures do.

Answer:

pH affects enzyme activity similarly to temperature. There's an optimal pH (e.g., pH 7 in the graph) where enzyme activity is maximum. Below or above this optimal pH, enzyme activity decreases. This is because, just like extreme temperatures, extreme pH values can denature the enzyme (alter its 3 - D structure), reducing its ability to bind substrates and catalyze reactions. At the optimal pH (and temperature), the enzyme has the proper shape for efficient substrate binding and reaction catalysis.
