Can you explain the significance of lactase persistence in adults and its impact on the ability to drink milk?
Lactase persistence in adults allows them to digest lactose, the sugar found in milk. This trait is significant because it enables individuals to continue consuming dairy products without experiencing digestive issues. This adaptation is common in populations with a history of dairy farming and consumption, providing a nutritional advantage.

What is the difference between lactase and lactose?
Lactase is an enzyme that breaks down lactose, which is a sugar found in milk and dairy products. In simple terms, lactase helps the body digest lactose.
What is an example of a favorable mutation?
An example of a favorable mutation is the development of lactase persistence in some human populations, which allows individuals to digest lactose into adulthood. This mutation provides a selective advantage in societies where dairy consumption is common.
If you are lactose intolerentwhat enzyme are you lacking?
If you are lactose intolerant, you are lacking the enzyme lactase. Lactase is responsible for breaking down lactose, the sugar found in milk and dairy products, into simpler sugars that can be easily absorbed by the body.
What coenzyme is in lactase?
It contains your face, and you useless lazy life, Pick up a book.
What is the chemical equation for lactose and lactase?
The chemical equation for the breakdown of lactose by lactase is: C12H22O11 (lactose) + H2O → C6H12O6 (glucose) + C6H12O6 (galactose). Lactase is the enzyme that catalyzes this reaction, breaking down lactose into its constituent monosaccharides, glucose, and galactose. This process is essential for the digestion of lactose in individuals who are lactose intolerant.
Is lactase heterogeneous?
Yes, lactase can be considered heterogeneous because it is an enzyme that varies in its expression levels and activity between different individuals. Some people have lactase persistence, allowing them to digest lactose effectively, while others have lactase non-persistence, which leads to lactose intolerance. This heterogeneity results from genetic differences and environmental factors.
What percentage of the worlds population suffers from lactose intolerance?
Most mammals normally cease to produce lactase, (and become lactose intolerant), after weaning. However, some human populations have developed lactase persistence (and therefore can eat dairy after adulthood). This said, research reveals intolerance to be more common globally than lactase persistence. The frequency of lactose intolerance ranges from 5% in Northern European to more than 90% in some African and Asian countries. That would mean that 95% of people form European stock and 10% of people from African and Asian stock are "not lactose intolerant".
For most of the worlds population what is the effect of aging on the activity of lactase?
As people age, their bodies often produce less lactase, the enzyme needed to digest lactose found in dairy products. This can lead to lactose intolerance, causing symptoms such as bloating, gas, and diarrhea when consuming dairy. However, lactase persistence, where the enzyme continues to be produced into adulthood, is more common in some populations.
Whats the function of the lactase substrate?
The function of the lactase substrate is to be acted upon by the enzyme lactase. Lactase breaks down lactose, the primary sugar found in milk, into its two component sugars, glucose and galactose, which can then be absorbed by the body for energy.
People with lactose intolerance produce insufficient amounts of?
the enzyme, lactase
What do you call the Enzyme that breaks down dairy sugar?
lactase
What lack of enzyme cause lactose intolerance?
The enzyme which the body uses to digest lactose is lactase.
What is the function of lactase?
Lactase is a digestive enzyme that is produced by the small intestine. The prime function of lactase is to digest a sugar compound called lactose. Yap, lactase is an enzyme that breaks down the disaccharide lactose yielding an end-product of glucose and galactose. It is important in digestion because the action of lactase yields glucose which is the primary sugar in the blood.

What enzyme act on Lactose?
The enzyme that acts on lactose is called lactase. Lactase breaks down lactose into its component sugars, glucose and galactose, which can then be absorbed by the body. People who are lactose intolerant have low levels of lactase, leading to difficulty digesting lactose.
Is lactase a protein?
Yes; Lactase is an enzyme (protein) that breaks down the sugar lactose found in milk.
