Question

renin is an enzyme that catalyzes a reaction that solidifies milk. renin was added to three different test - tubes with milk. each test tube was placed in a water bath for ten minutes. the data collected during the experiment are shown:

test tube	variable	result
2	room - temperature water bath	semi - solid milk
3	hot water bath	no solids, only liquid milk

which statement best explains the result of test tube 3?
a the enzyme changed the product.
b the substrate was used up.
c the enzyme was denatured.
d the substrate reacted with the enzyme.

Explanation:

Enzymes have optimal temperature ranges. High - temperature (hot water bath in test tube 3) can cause enzymes like rennin to denature, losing their structure and function, preventing the solidification of milk.

Answer:

C. The enzyme was denatured
