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

Answers

Answer:

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.

As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.

What is optimum temperature?

The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.

Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.

The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.

At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.

It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.

Thus, the correct option is C.

Terrestrial ecosystems are known for their diversity; they are grouped into large categories called biomes. Grouping these ecosystems into just a few biome categories obscures the great diversity of the individual ecosystems within them.
