Question

which is the most valid conclusion based on this graph? effects of temperature on enzyme activity enzymes work most effectively at low temperatures. raising the temperature always makes an enzyme work better. enzymes are not affected greatly by temperature. enzyme function decreases after a certain temperature.

Explanation:

The graph shows that enzyme activity first increases with temperature up to a certain point and then rapidly decreases after that optimal temperature. This indicates that enzyme function decreases after a certain temperature. Enzymes do not work most effectively at low - temperatures as activity is low initially. Raising temperature does not always make an enzyme work better as there is a point of denaturation. And enzymes are greatly affected by temperature.

Answer:

Enzyme function decreases after a certain temperature.
