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.

Answers

The average mass is 70 kg.

To find the average you need to add up all of the masses and divide by the total number of masses (7).

(55 + 60 + 60 + 65 + 70 + 85 + 95) / 7 =
490 / 7 = 70kg.

Answer:

D. light energy produced in earth's geosphere

Explanation:

Earth's internal heat budget is very important to Earth's thermal history. The heat flow from the earth's interior to the surface is estimated to be 47 ± 2 terawatts (TW) and originates from two main sources

The internal source of Earth's energy that helps drive convection currents below the crust is D. light energy produced in the earth's geosphere.

Convection current refers to the current that is formed as a result of differential heating. It should be noted that lighter warm material rises while the heavier cool material sinks.

The light energy that is produced in the earth's geosphere is necessary for driving convection currents below the crust. Energy is transferred through the oceans and the geosphere by convection.
