What is the main purpose of a sucrase?
Sucrase is an enzyme which catalyze the hydrolysis of sucrose to fructose and glucose.
What is sucrase secreted from?
Sucrase is a family of enzymes. Some of it is secreted from the salivary glands in the mouth but most of the sucrase activity is in the small intestines. In the intestines it is not secreted, but rather, contained in the wall.
What are two different ways by which hydrolysis can be brought about?
Hydrolysis can be brought about by adding water to a compound and allowing it to react, or by using an enzyme as a catalyst to speed up the hydrolytic reaction.
Where does sucrase work in the body?
Stomach
If lactase breaks down lactose and galactose then the enzyme sucrase breaks down?
The enzyme sucrase breaks down sucrose. Glucose and fructose are the products of this chemical reaction.
What is the substrate for lyase?
the substrate for lyase is sucrase
Is sucrose a substrate?
The Substrate for amylase are starch (amylose and Amylopectin), glycogen, and various Oligosaccharides.
What substrate would fit into the active site of sucrase?
The substrate would be sucrose. Normally a 5% sucrose solution.
Which component for the following reaction is substrate for sucrose surcase water sucrase glucose fructose?
sucrose
What conditions are necessary for the hydrolysis of sucrose?
in the hydrolysis of sucrose a catalyst such as sucrase must be applied
What enzyme digests sugars?
Sucrase is the enzyme (called a disaccharidase) that digests sucrose, the major disaccharide in table sugar.
Why does sucrase not hydrolyse lactose?
"because the reaction is to slow to make an effect, if a enzyme is added then it can hydrolyse lactose but it can take more than 6 years without the addition of an enzyme" Is bull**** the real answer is because the active site of the two substances are different and so the sucrase becasue Lactose has a different shape/structure which does not fit/bind to active site of enzyme/sucrase.
How do the enzymes affect digestion?
Enzymes break down specific molecules e.g. amalyse enzyme breaks down hydrogen peroxide, the substrate is on the molecule and then the enzyme comes along, the substrate goes in the active site, then it breaks the molecule down
Are catalyse Maltese and sucrose enzymes?
All enzymes end in -ase. Their substrate is the base for the enzyme. For example: the sugar maltose is acted on by the enzyme maltase. Sucrose, by sucrase.
What means enzyme?
The suffix -ase means an enzyme while the root of the word means the substrate that the enzyme is involved in. For example: sucrase is involved in the breaking down of the sugar sucrose.
What does it mean when it says enzymes are specific?
Enzymes are highly specific in their action. For example, enzyme maltase acts on sugar maltose and not on lactose or sucrose. Different enzymes may act on the same substrate but give rise to different products. For example, raffinose gives rise to melibiose and fructose in the presnce of enzyme sucrase while in the presence of enzyme melibiase it produces lactose and sucrose. Similarly an enzyme may act on different substrates like sucrase can act on both sucrose and raffinose producing different end products.
What do most enzymes end in?
Some thing then ase. So if the substrate was called B the enzyme would B+ase, Base. Or substrate Z, the enzyme would be Z+ase, Zase. Some examples, amylase, maltase, catalase, sucrase. That is the most common naming, but it is not ALWAYS the case.
