What enzyme synthesises starch from glucose -1- phosphate?
The enzyme that synthesizes starch from glucose-1-phosphate is starch synthase. This enzyme catalyzes the condensation reaction of glucose molecules to form the starch polymer.
In which step of glycolysis is an inorganic phosphate added?
The conversion of glyceraldehyde 3 phosphate to 1, 3 bisphosphoglycerate catalyzed byglyceraldehyde 3 phosphate dehydrogenase using NAD+ and Pi
What enzyme catalyzes the reaction that creates creatine phosphate?
The enzyme creatine kinase catalyzes the reaction that creates creatine phosphate. This reaction involves transferring a phosphate group from ATP to creatine, forming creatine phosphate and ADP. Creatine phosphate serves as a short-term energy reservoir in muscle cells.
What is glucose-6-phosphate dehydrogenase deficiency?
G6PD deficiency is caused by one copy of a defective G6PD gene in males or two copies of a defective G6PD gene in females. Hemolytic anemic attacks can be caused by oxidants, infection, and or by eating fava beans.
The breakdown of creatine phosphate is regulated by what?
The breakdown of creatine phosphate is regulated by the enzyme creatine kinase. This enzyme catalyzes the transfer of a phosphate group from creatine phosphate to ADP, forming ATP. The reaction is reversible, and the activity of creatine kinase helps to maintain energy balance in cells.
What two monosaccharides are formed when the lactase enzyme hydrolyzes lactose?
glucose and galactose http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/C/Carbohydrates.html
What enzyme synthesises starch from glucose -1- phosphate?
The enzyme that synthesizes starch from glucose-1-phosphate is starch synthase. This enzyme catalyzes the condensation reaction of glucose molecules to form the starch polymer.
What substrate is converted into glucose 6 phosphate by the enzyme hexokinase?
Glucose is the substrate that is converted into glucose 6-phosphate by the enzyme hexokinase. Hexokinase catalyzes the phosphorylation of glucose to glucose 6-phosphate in the first step of glycolysis.
The lack of which enzyme causes galactosemia?
The lack of the enzyme galactose-1-phosphate uridyltransferase (GALT) causes galactosemia. This enzyme is responsible for the breakdown of galactose in the body, and its deficiency leads to the accumulation of galactose and its toxic byproducts.
Which enzyme converts lactose to glucose and lactose?
The enzyme that converts lactose to glucose and galactose is lactase. Lactase is located in the brush border of the small intestine where it breaks down lactose into its two component sugars, glucose and galactose, which can then be absorbed into the bloodstream.
Which enzyme in glycolysis is responsible for the conversion of glucose to glucose 6-phosphate?
Hexokinase
What type of mutations causes galactosemia?
Galactosemia is primarily caused by mutations in the GALT gene, which encodes an enzyme called galactose-1-phosphate uridylyltransferase. Mutations in this gene result in reduced or absent enzyme activity, leading to the accumulation of galactose-1-phosphate in the body.
Is compose of one glucose plus one galactose molecule?
Lactose is composed of one glucose molecule and one galactose molecule bonded together. Upon digestion by the enzyme lactase, lactose is broken down into its individual glucose and galactose molecules for absorption in the body.
What is the combination of glucose and galactose?
The combination of glucose and galactose forms lactose, which is a disaccharide commonly found in milk. Lactose is broken down by the enzyme lactase into its constituent monosaccharides during digestion.
What obtained as hydrolysis product of lactose?
Lactose is a disaccharide composed of glucose and galactose. Upon hydrolysis, lactose breaks down into its component monosaccharides, glucose, and galactose. This process is catalyzed by the enzyme lactase.
What enzyme is person who is lactose intolerant missing?
Lactose intolerance is the inability to efficiently convert lactose into glucose and galactose, a reaction catalyzed by the enzyme lactase. (A rule of thumb for enzyme nomenclature is that many enzyme names typically take most of the name of their substrate and slap an "-ase" at the end.)
Galactose is a product of enzymatic hydrolysis of?
Galactose is obtained from lactose (the milk sugar) after its hydrolysis carried out by the enzyme beta-galactosidase (or lactase) yielding beta-D-glucose and alpha-D-galactose.
