What percentage of the world's population loses the ability to produce the enzyme lactase with age?
About 75% (three-quarters) of all adults produce less lactase as they grow older.
This is only an approximate figure. In parts of Europe it is about 5%, and in parts of Asia above 90%.
The condition is known as lactose intolerance, because without the enzyme people cannot digest the sugar lactose. The lactose is therefore not absorbed and travels further along the gut, where bacteria act on it and produce gases, which cause considerable discomfort.
Lactose is particularly found in milk, and people with lactose intolerance have to avoid dairy foods as far as possible.
What else can I help you with?
People with lactose intolerance produce insufficient amounts of?
the enzyme, lactase
What chemical in milk is not healty?
Milk contains a sugar called Lactose which all (the vast majority) of child can digest as they produce a enzyme called Lactase which metabolizes it. In a good deal of adult the ability to produce Lactase is lost and the presence of milk in the intestines leads to painful conditions. I hesitate to call Lactose unhealthy but in certain conditions it is.
Does pancreas produce lactase?
No, the pancreas does not produce lactase. Lactase is an enzyme that is primarily produced in the small intestine, specifically by the cells lining the intestinal villi. Its main function is to break down lactose, the sugar found in milk, into glucose and galactose for easier absorption. The pancreas is responsible for producing enzymes that aid in the digestion of carbohydrates, proteins, and fats, but not lactase.
What normally happens to the levels of lactase produced throughout a persons lifetime?
Lactase production typically declines after weaning, as many individuals lose the ability to digest lactose in adulthood. This decrease varies among populations, with some maintaining higher lactase levels due to genetic adaptations linked to dairy consumption. In lactose-intolerant individuals, lactase levels drop significantly, leading to difficulties in digesting lactose found in dairy products. Conversely, those with lactase persistence continue to produce the enzyme into adulthood, allowing them to digest lactose without issues.
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.
Will lactose intolerance occur individuals that do not have the enzyme maltase?
no, this only happens when you insufficiently produce lactase.
What is the measure ability to survive and produce more offspring relative to other members of the population called?
Fitness is a term that is used to measure the ability to survive and produce the most offspring.
What is the measure of the ability to survive and produce more offsring relative to other members of the population called?
fitness
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".
How does lactid help with lactase intolerance?
It helps with lactose intolerance because contains the enzyme Lactase which if you are Lactose intolerant you body doesn't produce this enzyme and the enzyme lactase in Lactaid pills breaks down the milk sugar(Lactose) making it easier for your body to digest dairy foods. Taken off of my box of Lactaid
What organelle has the problem if lactose digestive enzymes not produced?
Lysosome. Which fails to produce the enzyme lactase. (source : medical forum)
What type of organisms is enzyme lactase present?
Lactase is an enzyme primarily found in mammals, where it is produced in the small intestine to aid in the digestion of lactose, the sugar found in milk. It is especially abundant in infants, allowing them to digest breast milk. Some bacteria and fungi also produce lactase, although it is less common in these organisms compared to mammals.
