Question

The first step in lactose metabolism is catalyzed by.

Answer 1

Lactose Metabolism Is Catalyzed By:

1. Jacob and Monod originally authored the term ''operon'' in the wake of recognizing the first traditional operon, the lac operon, which was found in E.coli.
2. The lac operon contains 3 primary qualities important to being utilized for lactose, they are - lacA, lacY, and lacZ. Such qualities encode a lac permease, beta-galactosidase, and transacetylase, separately.
3. The initial phase in lactose digestion is catalyzed by beta-galactosidase. It partitions lactose into glucose and galactose.
4. Then, at that point, lactose is consumed by lac permease, a transmembrane protein.
5. The transacetylase then moves an acetyl bunch from the coenzyme A to the hydroxyl gathering of the galactosides.
