Question

the enzyme beta - galactosidase works best at 37°c. under optimal conditions, the enzyme beta - galactosidase looks like this: which of the following images best represents what beta - galactosidase looks like at 4°c a. b. c. image a image c image b

Explanation:

Enzymes are proteins and their structure is temperature - sensitive. At temperatures lower than the optimal temperature ($4^{\circ}C$ is lower than the optimal $37^{\circ}C$ for beta - galactosidase), the enzyme may start to denature. Denatured enzymes lose their native, well - defined shape. Image c shows a disordered shape which is characteristic of a denatured enzyme. Images a and b still have a defined shape similar to the native form.

Answer:

C. image c
