Look at the graph...What is the optimal temperature for this enzyme? A. 60 degrees C

B. 45 degrees C

C. 15 degrees C

D. 35 degrees C

B: 45 degrees C

Explanation:

the enzyme performs best at 45°C and starts to denature at 50°C

B: 45 degrees C

Explanation:

However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.

explanation:

yes you are doing it right great gob
