Through What Type Of Reaction Are Disaccharides Catabolized To Monosaccharides?


What type of reaction occurs when a disaccharides Catabolized to monosaccharides?

Breaking apart a double sugar into its two monosaccharides is accomplished by hydrolysis with the help of a type of enzyme called a disaccharidase. As building the larger sugar ejects a water molecule breaking it down consumes a water molecule. These reactions are vital in metabolism.

What reactions represents dephosphorylation?

Dephosphorylation involves removal of the phosphate group through a hydration reaction by addition of a molecule of water and release of the original phosphate group regenerating the hydroxyl. Both processes are reversible and either mechanism can be used to activate or deactivate a protein.

What is the name of the molecule that results from the removal of two phosphate from ATP quizlet?

When phosphate is removed energy is released and ATP becomes ADP.

What is the end product after glucose undergoes aerobic glycolysis?

Since virtually all sugars are ultimately convertible to glucose glycolysis serves as the hub of carbohydrate metabolism. In cells with mitochondria and an adequate supply of oxygen pyruvate emerges as the end product of glycolysis via a 10-reaction series known as aerobic glycolysis.

What digests disaccharides into monosaccharides?

The disaccharides are broken down into monosaccharides by enzymes called maltases sucrases and lactases which are also present in the brush border of the small intestinal wall. Maltase breaks down maltose into glucose.

How can a disaccharide be converted into monosaccharides?

As disaccharides travel through the body they are broken down into simple sugars or monosaccharides by a process called hydrolysis. This process is facilitated by enzymes called maltases sucrases and lactases. These different enzymes help to break down different types of sugars in the body.

What is dephosphorylation in biology?

: the process of removing phosphate groups from an organic compound (such as ATP) by hydrolysis also : the resulting state.

Which of the following enzymes is activated by dephosphorylation?

Dephosphorylation is performed by enzymes known as phosphatases which resemble kinases except that they remove the phosphate group (Fig. 1).

What is the enzyme attaches a phosphate to glucose?

The first step in glycolysis is catalyzed by hexokinase an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate producing glucose-6-phosphate a more reactive form of glucose.

When a phosphate group is removed from an ATP molecule quizlet?

What happens when a phosphate group is removed from an ATP molecule? When a phosphate group is removed from ATP energy is released and ADP results. What is ATP and when is energy released from it? ATP is converted into ADP and a phosphate group.

When a phosphate group is removed from an ATP molecule what molecule is formed?

When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis energy is released and ATP is converted to adenosine diphosphate (ADP).

What molecule is formed from the parts that are removed?

Again what molecule is formed from the parts removed in making these connections? This new compound with one fewer phosphate groups than before is called adenosine diphosphate (ADP).

What kind of reaction joins together two monosaccharides to form a disaccharide such as sucrose?

Sucrose (table sugar) and Lactose. Formation[edit] Disaccharides are formed when two monosaccharides join together by the dehydration synthesis reaction resulting in a glycosidic bond between the two monosaccharide molecules. The reaction produces water as a side product.

What happens to glucose molecules during the process of glycolysis?

During glycolysis glucose ultimately breaks down into pyruvate and energy a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).

What are end products of glycolysis?

Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules a total of four ATP molecules and two molecules of NADH.

How are monosaccharides digested?

The monosaccharides are absorbed into the bloodstream and delivered to the liver. Some of the indigestible carbohydrates are digested by bacteria in the large intestine. Glucose itself participates in regulating its levels in the blood.

How are polysaccharides and disaccharides digested?

Polysaccharides and disaccharides are digested by different enzymes produced in the digestive tract. The polysaccharides are broken down to oligosaccharides and the simple sugars are disaccharides that are further digested to form monosaccharides.

When disaccharides are broken into monosaccharides What is the process involved Brainly?

When disaccharides are changed into monosaccharides hydrolysis reaction takes place. Explanation: usually disaccharides are broken down into monosaccharides to make it easy for digestion of different types of carbohydrate.

Which functional group is formed during the reaction between 2 monosaccharides to form a disaccharide?

Disaccharide is a carbohydrate which is formed when two monosaccharides undergo a condensation reaction with the elimination of a single molecule of H2O from the functional groups. Like monosaccharides disaccharides form an aqueous solution when dissolved in water.

What enzymes break down disaccharides?

The digestion of disaccharides and some oligosaccharides is undertaken by a number of small intestinal brush border enzymes: sucrase-isomaltase lactase phlorizinhydrolase maltase-glycoamylase and trehalase.

What is the chemical formula of disaccharide?

Similar to other carbohydrates disaccharides are comprised of hydrogen carbon and oxygen and the ratio of hydrogen atoms to oxygen atoms is often 2:1 which explains why they are referred to as hydrates of carbon. The general chemical formula of disaccharides is C12H22O11.

What type of molecule is hexokinase?

A hexokinase is an enzyme that phosphorylates hexoses (six-carbon sugars) forming hexose phosphate. In most organisms glucose is the most important substrate for hexokinases and glucose-6-phosphate is the most important product.

What types of enzymes perform phosphorylation and dephosphorylation?

Phosphorylation is the chemical addition of a phosphoryl group (PO3) to an organic molecule. The removal of a phosphoryl group is called dephosphorylation. Both phosphorylation and dephosphorylation are carried out by enzymes (e.g. kinases phosphotransferases).

What makes up a phosphate group?

Phosphate group: A functional group characterized by a phosphorus atom bonded to four oxygen atoms (three single bonds and one double bond). One of these oxygen atoms must be bonded to another atom if not the structure is a phosphate ion.

What kind of enzyme adds a phosphate group from a protein?

kinase an enzyme that adds phosphate groups (PO43−) to other molecules. A large number of kinases exist—the human genome contains at least 500 kinase-encoding genes. Included among these enzymes’ targets for phosphate group addition (phosphorylation) are proteins lipids and nucleic acids.

What kind of enzyme removes a phosphate group from a protein quizlet?

A phosphatase enzyme removes the phosphate groups from the target proteins.

What kind of enzyme removes a phosphate group from a protein?


A phosphatase is an enzyme that removes a phosphate group from a protein. Together these two families of enzymes act to modulate the activities of the proteins in a cell often in response to external stimuli.

What does hexokinase do in glycolysis?

Hexokinase is the initial enzyme of glycolysis catalyzing the phosphorylation of glucose by ATP to glucose-6-P. It is one of the rate-limiting enzymes of glycolysis. Its activity declines rapidly as normal red cells age.

What enzymes are in glycolysis?

The three key enzymes of glycolysis are hexokinase phosphofructokinase and pyruvate kinase. Lactate dehydrogenase catalyzes the transfer of pyruvate to lactate.

What is the chemical reaction of glycolysis?

The net equation for glycolysis is as follows: C6H12O6 + 2 ADP + 2 [P]i + 2 NAD+ –> 2 pyruvate + 2 ATP + 2 NADH where C6H12O6 is glucose [P]i is a phosphate group NAD+ and NADH are electron acceptors/carriers and ADP is adenosine diphosphate.

When a phosphate is added to a molecule?


Adding a phosphate to a molecule is called phosphorylation. What two methods do cells use to phosphorylate ADP into ATP?

Which best describes what happens when a phosphate molecule is removed from an ATP compound quizlet?

A phosphate is removed from an ATP molecule in order to provide energy for the cell. Thus the ATP molecule turns into an ADP molecule. We eat food which gives us energy to add another phosphate group to the ADP molecule turning it into an ATP molecule.

Where does the energy to add a phosphate group to ADP to form ATP come from?

Energy derived from glucose catabolism is used to convert ADP into ATP. When ATP is used in a reaction the third phosphate is temporarily attached to a substrate in a process called phosphorylation.

What type of reaction is ADP to ATP?

ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.
