What enzyme breaks down starch into sugars which are than broken down by the other three enzymes?
starch can be broken down into simple sugars by the enzyme amylase
What happens when lactase is added to lactose?
When enzymes are boiled they become denatured, meaning they lose their function because they lose their shape. Any change in temperature or pH other than the one they are accustomed to will disturb an enzyme's shape; simply reverse their environment changes, and they'll go back to their correct function.
What is the purpose of lactase?
When we use the "ase" ending for a chemical, especially in a biological sense, we are talking about an enzyme. Which is a protein that enables a chemical change not otherwise possible. It is a biological catalyst. Each single reaction that requires an enzyme is different so there is a different enzyme for every kind of reaction needed! We name the enzymes after the chemical they act on. Cellulase is a chemical produced by cows that acts on cellulose (see how similar they look?) which is the main structural component of plants. (By the way, the "ose" ending means a starch or a sugar, like glucose, fructose, amylose....) This allows the cow to digest tough plant material that humans would need to cook before eating (leaves) or cannot eat at all (hay.)
Why would having an enzyme lactase as an adult be an evolutionary advantage?
Having the enzyme lactase as an adult provides an evolutionary advantage by allowing individuals to digest lactose, the sugar found in milk, beyond infancy. This ability enables adults to utilize dairy products as a rich source of nutrition, particularly in environments where other food sources may be scarce. Additionally, the consumption of milk can support hydration and provide essential vitamins and minerals, contributing to overall health and reproductive success, which can enhance survival and fitness in certain populations.
What is the cause of adrenal hyperplasia?
Adrenal hyperplasia is primarily caused by genetic mutations that affect the adrenal glands' ability to produce hormones. The most common form, congenital adrenal hyperplasia (CAH), is usually due to a deficiency in the enzyme 21-hydroxylase, leading to an imbalance in steroid hormone production. This results in excess androgens and can cause various symptoms, including ambiguous genitalia in newborns and precocious puberty. Other less common forms may involve different enzyme deficiencies or genetic factors affecting adrenal function.
What are some common enzymes?
Lactase is a common enzyme that breaks down lactose. Other common enzymes are diastase with aids in breaking down vegetable starch, sucrase which digests sugars, and protease which breaks down proteins
Why did the enzyme lactase react with lactose but not sucrose?
Because, lactase breaks beta(1-4) glycosidic bonds between a galactose and a glucose, while sucrose molecule is formed by a dimer of a glucose and a fructose linked by an alpha(1-2) glycosidic bond.
Does the lactase enzyme hydrolyze substrates other than lactose?
Yes it does more than commonly believed. Lactose is just one of the Beta 1to4 "O" glycosides hydrolyzed by the lactase enzyme which is and incorrect nomenclature for the enzyme that is a Beta 1to4 "O" glycosidase. Many who clal them selves experts use the term lactase instead of Beta 1to4 "O" glycosidase due to flase thinking on the matter. Phlorizin, annatto, pectin, tomatine, salicin, various gums and solanine are but a few of those beta 1to4 "O" glycosides that the enzyme Beta 1to4 "O" glycosidase will hydrolyze. E.coli that lives on the proximal and distal sides of the eleocecal valve in humans will ferment, cleave, oxygen and carbon for the reducing end of the glycoside that is part of the aglycones above mentioned.
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.
Why is the digestion of milk affected by lactose found in the stomach?
Are you talking about lactose intolerance? If so, people are lactose intolerant because they do not have the enzyme lactase that is use to digest the lactose. The gene that codes for the lactase cease to be express when they get older . Other people keep expressing the gene for their entire life.

Can lactase act on any other sugar besides lactose?
It is possible for lactase to act on other sugars besides lactose. One specific sugar is the sucrose. However, most acts have problems digesting other forms of sugars.

What causes lactose intolerance?
lactose intolerance is caused by reduced or absent activity of lactase that prevents the splitting of lactose. it also occures when the small intestine does not produce enough enzyme called lactase. your body needs lactase to break down, or digest lactose.
