Web23 Dec 2009 · Experimental data show that the effect of temperature on enzymes cannot be adequately explained in terms of a two-state model based on increases in activity and denaturation. The Equilibrium Model provides a quantitative explanation of enzyme thermal behaviour under reaction conditions by introducing an inactive (but not denatured) … WebAt stage 2, the enzyme activity is at its peak, I believe around 40 degrees. At stage 3, the enzyme is becoming denatured from the high temperatures, and is losing its unique shape, which allows it to catalyse substances. At stage 4, the high temperatures have completely denatured the enzyme, making it ineffective as a catalyst. 20o Variables
