What reaction is in the first reaction of glycolysis receives a phosphate group from ATP?
In the first reaction of glycolysis, glucose is phosphorylated to form glucose-6-phosphate. This reaction is catalyzed by the enzyme hexokinase (or glucokinase in the liver) and involves the transfer of a phosphate group from ATP to glucose. This phosphorylation is crucial as it helps to trap glucose within the cell and prepares it for further breakdown in the glycolytic pathway.
What happens to the phosphorylated glucose in glycolysis?
Glutamic acid covalently bonded with a phosphate group
What binds the phosphate group to the next group?
In a nucleic acid, the phosphate group is bound to the next group (either another phosphate or a sugar) by a phosphodiester bond. This bond forms between the phosphate group's phosphate (-PO4) and the hydroxyl group (-OH) of the next group. The bond is formed through a dehydration reaction, where a water molecule is removed.
What is the reaction that turns glucose into sodium gluconate?
The reaction that turns glucose into sodium gluconate is an oxidation reaction using an oxidizing agent such as sodium hypochlorite or hydrogen peroxide. This reaction converts the aldehyde group of glucose into a carboxylic acid group, resulting in the formation of sodium gluconate.
What does glucose need to enter the cell?
1. Glucose enters the cell by simple diffusion across the membrane. The addition of a bulky polar group like phosphate prevents it from diffusing right back out. 2. This is the first phosphate group that will contribute to the formation of glyceraldehyde-3-phosphate (GAP), an important intermediate in glycolysis.
What reaction is in the first reaction of glycolysis receives a phosphate group from ATP?

This phosphorylation is crucial as it helps to trap glucose within the cell and prepares it for further breakdown in the glycolytic pathway.
Describe the first reaction in glycolysis Is this reaction catalyzed by an enzyme?
The first reaction in glycolysis is the phosphorylation of glucose to glucose-6-phosphate by the enzyme hexokinase. This reaction involves the transfer of a phosphate group from ATP to glucose, requiring energy for activation.
What does the first process of glycolosis produce?
Glycolosis is a metabolic reaction which converts glucose into pyruvate. The first step involves the phopsphate transfer from ATP group to glucose, thus formin glucose 6 phosphate.
What is a coupled reaction using as an example the conversion of glucose to glucose-6-phosphate?
A coupled reaction is two reactions that occur together. One reaction is necessary for the other to occur.The conversion of glucose to glucose-6-phosphate is a good example. The first step that the cell takes in glycolysis (the beginning of the cellular respiration of glucose) is to convert glucose into glucose-6-phosphate. This phosphorylation requires an energy input, and therefore will not occur spontaneously.In the cell, both the necessary energy and the phosphate group are provided by a molecule of ATP. The free energy released by the conversion of ATP into ADP and a phosphate ion (Pi) is far greater than the energy required for the phosphorylation of glucose, and so, when the two reactions are coupled together, the phosphorylation of glucose goes ahead.To couple these reactions a hexokinase is required. This enzyme needs magnesium as a cofactor.
Name one reaction were ATP is required?
The first reaction of glycolysis, where glucose is phosphorylated (a phosphate group is added) to give glucose - 6 - phosphate requires ATP. This reaction is catalyzed by the enzyme hexokinase
Which kind of chemical reaction involves the attachment of removal of a phosphate group?
A phosphorylation reaction involves the addition of a phosphate group, while dephosphorylation involves the removal of a phosphate group. These reactions are crucial for regulating protein activity and cell signaling pathways.
What molecule never contains a phosphate group?
Quite a few fit that description (including water, carbon dioxide, borane etc.)
What happens to the phosphorylated glucose in glycolysis?
Glutamic acid covalently bonded with a phosphate group
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.
The formation of ADP and inorganic phosphate from ATP and water is an example of which kind of reaction?
The formation of ADP and inorganic phosphate from ATP and water is an example of a hydrolysis reaction. In this reaction, a water molecule is used to break the bond between the phosphate group and ATP, resulting in the formation of ADP and inorganic phosphate.
What binds the phosphate group to the next group?
In a nucleic acid, the phosphate group is bound to the next group (either another phosphate or a sugar) by a phosphodiester bond. This bond forms between the phosphate group's phosphate (-PO4) and the hydroxyl group (-OH) of the next group. The bond is formed through a dehydration reaction, where a water molecule is removed.
