Investigators studied the effect of temperature on the rate of biological enzyme action. The experimental data is summarized in
the graph. The investigators concluded that the enzyme works best at human body temperature. What part of the data validates their conclusion?
The graph peaks at 37°C and dips beyond this point.
B) The graph shows an exponential rise in reaction velocity.
C) The graph shows that the reaction is complete at 60°C.
D) The reaction is seen for temperatures between 0°C and 60°C.
The graph peaks at 37°C and dips beyond this point.
Explanation:
Imagine that temperature is on the x axis and rate of biological enzyme action is on y axis. Now as the temperature changes it is seen that the rate of biological enzyme action increases and is maximum at body temperature which is 37°C. Increasing the temperature does not change the rate of biological enzyme action. Which means there is no peak beyond 37°C.
Since the car is at rest, the force experienced by car will be normal face(exerted by surface to which car is in contact) and weight of the car. As the car is at rest, net force on the car should be zero.
