Question

which is the most valid conclusion based on this graph? enzyme activity 10 20 30 40 50 60 temperature (°c) enzymes function most efficiently at high temperatures. enzyme action is constant regardless of temperature. enzyme action decreases after a certain favorable temperature. enzymes require low temperatures in order to function.

Explanation:

The graph shows enzyme activity increasing with temperature up to a peak, then decreasing. This indicates that after a certain favorable temperature, enzyme action decreases.

Answer:

Enzyme action decreases after a certain favorable temperature.
