Lactase is an enzyme, it wraps around the lactose (the part that wraps around the lactose is known as the active site) substrate and cuts it up into smaller pieces galactose and glucose

What does lactose do?

Firstly, I think you phrased this question wrong because lactose is a substrate. It is the job of lactase (and enzyme) to break down lactose. Some people are lactose intolerant because their bodies do not have enough lactase enzymes to break down lactose.


What kind of substance is lactase?

lactase is a substance that helps break down lactose into sugars (glucose and galactose).


If a person is lactose intolerant their body cant absorb what?

Their body can't absorb lactose...There are enzymes in your small intestine which break down lactose called lactase. Lactase breaks down lactose into galactose and glucose so your body can then absorb it.


Why doesnt the lactase in lactose intolerant people work?

Lactose intolerant people have a deficiency of an enzyme called lactase, which breaks up the lactose into two monosaccharides called galactose and glucose. These two are easily digestable, whereas lactose is not.


Whats the function of the lactase substrate?

Lactase is the bodily enzyme that breaks down Lactose, a sugar found in milk.


Is lactase breaking down lactose dehydration or hydrolosis?

lactase catalyses hydrolysis of lactose.


What sugar is responsible for lactose intolerance?

Galactose is involved with lactose intolerance, but is not responsible for lactose intolerance. The enzyme that is missing or is not found in great enough quantities in the body, lactase, is responsible for not breaking down lactose. This is how the intolerance comes about. The body cannot properly break down lactose without the enzyme lactase present.


Where is lactose broken down in the body?

Lactose is broken down in the body by an enzyme called lactase, which is produced in the small intestine. Lactase breaks down lactose into its two component sugars, glucose and galactose, which can then be absorbed by the body for energy. If a person is deficient in lactase, they may experience lactose intolerance.


Which enzyme converts lactose to glucose and lactose?

Lactase is the enzyme that breaks down lactose.


What does the lactase enzyme help with the digestion of?

Lactase enzymes are produced by the body to help the digestion of whole milk. Lactase enzymes break down Lactose one of the main components of milk and dairy products.


What happens when milk is treated with lactase?

Lactase is an enzyme that breaks down lactose in milk. This allows lactose intolerant individuals to drink the lactose free (or reduced lactose) milk.


What does Escherichia coli need to break down lactose?

It needs to code for the enzyme lactase in its DNA, which in turn breaks the bond between the two sugars in lactose
