What happens to most enzymes at high temperature, such as 80 degrees Celsius?
Answer and explanation
Correct answer: C. They are denatured
- Step 1: An enzyme works through its three-dimensional shape. Step 2. High temperature breaks the bonds that hold that shape. Answer: denaturation. Why not the others: heat speeds reactions only up to the optimum, and enzymes do not become substrates.
