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:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.
