35 diagram and describe the lactose and lactase reaction

The lactose operon (lac operon) is an operon required for the transport and metabolism of lactose in E. coli and many other enteric bacteria.Although glucose is the preferred carbon source for most bacteria, the lac operon allows for the effective digestion of lactose when glucose is not available through the activity of beta-galactosidase. With the aid of the enzyme, lactase, the substrate, lactose, is broken down into two products, glucose and galactose. People who don't make enough lactase have ...

Following Buchner's example, enzymes are usually named according to the reaction they carry out: the suffix -ase is combined with the name of the substrate (e.g., lactase is the enzyme that cleaves lactose) or to the type of reaction (e.g., DNA polymerase forms DNA polymers). The biochemical identity of enzymes was still unknown in the early 1900s.

Milk containing lactose Jelly beads with lactase enzyme attached The lactase splits the lactose into smaller sugar molecules Lactose free milk Beaker (a) (i) Underline one option in each of the brackets to make the following sentences correct. What does lactase do and how? In a way, enzymes are the main “workhorses” of metabolism: they catalyse all the life-sustaining chemical reactions, ...4 pages b. Endergonic or exergonic? 1. Remember, lactase is an enzyme, and we describe enzymes as catalysts: a substance that helps chemical reactions happen without being used up. Lactase only is able to break lactose down and sucrose due to the differing shapes of each sugar.
