Answer:
Temperature of 100°C increase the reaction rate, due to the rise of the energetic collision between molecules that increase the collision, compared to the same reaction at 21 °C, who has less energy and for that reason will be more slow to react.
Explanation:
The enzymatic reactions are reactions between organic molecules named as substrate and some proteic biological structures called enzymes. These reactions can be simplified as a regular chemistry process between reagents to obtain a product, that in this case is the transformations of the substrate.
So we can use the following process:
Enzyme (E) + substrate (S) = product (P)
Of course, this an uncomplex way to see this process, just to understand this example. In reality, the product or these reactions involves a transformation of the substrate and the enzyme. But for now, let's just use this equation
Using just the letters:
E + S = P
Now, we can use the concept of rate or velocity on chemical equations to analyze the effect of temperature in the enzymatic reactions:
Remember that for any chemistry reactions, the rate depends on the capacity of the molecules to collide, these collisions will be major when the reagents have enough kinetic energy to move around and interact between them. The frequency of these collisions is affected by different variables such as temperature.
Temperature is equal to energy, so if to reactions are supplied by external energy like thermic energy, the molecules, in this case, enzyme and substrate can move faster, and the collides can be more frequent when the temperature increases.
In conclusion, the increases in temperature to 100°C, increase the reaction rate, due to the rise of the energetic collision between molecules that increase the collision, and are these who result in the product of a enzymatic reactions, compared to the same reaction at 21 °C, who has less energy and for that reason will be more slow to react.
