Question

which best explains how high temperatures affect enzymes and substrates? a. high temps. increase the substrate concentration and cause enzymes to be produced b. high temperatures unfold the substrate and allow enzymes to combine with them c. high temperatures denature enzymes and stop them from combining with substrates d. high temps. activate the enzymes and allow additional substrates to be attracted to them

Explanation:

Enzymes are proteins. High temperatures break the weak bonds that maintain their 3 - D structure, causing denaturation. Denatured enzymes lose their active - site shape and cannot bind to substrates.

Answer:

C. High temperatures denature enzymes and stop them from combining with substrates
