Question

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

Explanation:

Enzymes have an optimal pH (like optimal temperature) where activity is highest. Deviating from this pH (similar to temperature extremes) disrupts enzyme structure (denaturation). Just as extreme temperatures reduce enzyme activity, extreme pH values (too acidic or basic) lower enzyme activity. The graph shows a peak (optimum pH) with activity decreasing on either side, similar to temperature - activity graphs where there's an optimal temperature and activity drops at non - optimal temps.

Answer:

pH affects enzyme activity similarly to temperature. There's an optimal pH (like optimal temperature) where enzyme activity is maximum. At pH values lower or higher than the optimum (analogous to temperatures below or above the optimal temperature), enzyme activity decreases. This is because extreme pH, like extreme temperature, can disrupt the enzyme's structure (denaturation). Just as temperature - activity graphs show a peak at the optimal temperature with decreasing activity on either side, the pH - activity graph (Graph 3) shows a peak at the optimum pH with decreasing activity as pH moves away from this optimum in either the acidic or basic direction.
