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.
What else can I help you with?
Is coupled transport an example of active or passive transport?
Coupled transport is an example of active transport.
What is an example of a reduction reaction?
An example of elimination reaction is seen in the reaction of isobutylbromide with potassium ethoxide in ethanol. Isobutylene, ethanol and potassium bromide is the resulting reaction.
Is burning wood an example of an exergonic or endergonic reaction?
Yes, combustion is an example of an exergonic reaction. During combustion, energy is released- making it an exergonic reaction.
A reaction that releases energy in the form of heat?
An exothermic reaction releases energy in the form of heat. This type of reaction typically results in a rise in temperature in the surrounding environment. Examples include combustion and neutralization reactions.
Example of active site?
An example of an active site is the binding pocket in an enzyme where a substrate molecule can bind and undergo a chemical reaction. This active site has specific amino acid residues that interact with the substrate, allowing the enzyme to catalyze the reaction.
Is coupled transport an example of active or passive transport?
Coupled transport is an example of active transport.
Hitler had a hysterical conversion reaction when he went 'blind' during World War 1 He was used a a teaching subject in the medical school Why is this not used as a good example of his mental illness?
The question makes a lot of assumptions. For example, it assumes that Hitler 'had a hysterical conversion reaction' and that this is 'a good example of his mental illness'. 1. The 'reaction' referred to is not documented. There are no case notes. 2. It is assumed that he was mentally ill. On what grounds? He he ever consult a psychiatrist after leaving the army?
Why is the conversion of lactose to glucose an example of a hydrolytic reaction?
The conversion of lactose to glucose is a hydrolytic reaction because it involves breaking a bond in lactose using a water molecule. This results in the separation of lactose into its constituent parts, glucose and galactose, through the addition of a water molecule in the process.
What is an example of a reduction reaction?
An example of elimination reaction is seen in the reaction of isobutylbromide with potassium ethoxide in ethanol. Isobutylene, ethanol and potassium bromide is the resulting reaction.
Is the conversion of NAD to NADH an example of oxidation or reduction?
The conversion of NAD to NADH is an example of reduction.
Is exothermic reaction an example of photosynthesis?
An exothermic reaction is a reaction where heat or light energy is released. An example of this type of reaction is burning a candle.
Discuss the SN reaction with example?
The SN reaction is a substitution reaction. An example of the SN reaction is Br. H3CH2C.
The hydrolysis of ATP that often occurs simultaneously with the synthesis of many compounds is an example of?
The hydrolysis of ATP is an example of an exergonic reaction, releasing energy stored in the phosphate bonds. This released energy can be used to drive cellular processes such as biosynthesis, muscle contraction, and active transport.
What is an energy conversion that involves chemical energy?
The conversion of chemical energy into thermal energy through combustion is a common example. Burning wood or gasoline releases the stored chemical energy in the form of heat and light energy.
Is a change in mass an indicator of chemical reaction?
A change in mass can be an indicator of a chemical reaction if there is a conversion of reactants into products with different mass compositions. For example, if gas is released during a reaction or if there is a change in the number of moles of substances present, there may be a noticeable change in mass.
What is striking a match an example of?
Striking a match is an example of an endothermic reaction. It is also an example of simple combustion and a chemical reaction.
Is photosynthesis an example of an endothermic reaction yes or no?
No, photosynthesis is not an example of an endothermic reaction. It is an example of an exothermic reaction because it releases energy in the form of glucose and oxygen.
