7.7: Coupled Reactions - Chemistry LibreTexts

https://chem.libretexts.org/Courses/Mount_Royal_University/Chem_1202/Unit_7%3A_Principles_of_Thermodynamics/7.7%3A_Coupled_Reactions
Coupled Reactions in Biology. This is a common feature in biological systems where some enzyme-catalyzed reactions are interpretable as two coupled half-reactions, one spontaneous and the other non-spontaneous. Organisms often the hydrolysis of ATP (adenosine triphosphate) to generate ADP (adenosine diphosphate) as the spontaneous coupling

https://www.khanacademy.org/science/ap-biology/cellular-energetics/cellular-energy/a/atp-and-reaction-coupling
When two reactions are coupled, they can be added together to give an overall reaction, and the ΔG of this reaction will be the sum of the ΔG values of the individual reactions. As long as the overall ΔG is negative, both reactions can take place. Even a very endergonic reaction can occur if it is paired with a very exergonic one (such as

- [Instructor] Coupled reactions use a thermodynamically favorable reaction to drive a thermodynamically unfavorable reaction. For example, let's look at a hypothetical reaction where reactants A and B combine to form products C and i. The standard change in free energy for this reaction, delta G naught, let's say, is greater than zero.

Coupling reaction - Wikipedia

https://en.wikipedia.org/wiki/Coupling_reaction
Coupling reaction. In organic chemistry, a coupling reaction is a type of reaction in which two reactant molecules are bonded together. Such reactions often require the aid of a metal catalyst. In one important reaction type, a main group organometallic compound of the type R-M (where R = organic group, M = main group centre metal atom) reacts

What is a coupled reaction and why do cells couple reactions?

https://biology.stackexchange.com/questions/2051/what-is-a-coupled-reaction-and-why-do-cells-couple-reactions
A reaction where the the free energy of a thermodynamically favorable transformation, such as the hydrolysis of ATP, and a thermodynamically unfavorable one, are mechanistically joined into a new reaction (or may be envisaged to be so joined) is known as a coupled reaction.. To put it another way, two or more reactions may be combined mechanistically such that a spontaneous reaction may be

T he equilibrium constant for a reaction written backwards is the reciprocal of the constant for the reaction written in the forward direction. aA ⇌ bBK forward. The equilibrium constant of two or more coupled reactions is the product of the equilibrium constant for each coupled step. aA ⇌ bB K1 = [B]b [A]a bB ⇌ cC K2 = [C]c [B]b the sum

3.22: Coupled Reactions. Cellular processes such as building and breaking down complex molecules occur through stepwise chemical reactions. Some of these chemical reactions are spontaneous and release energy, whereas others require energy to proceed. Cells often couple the energy-releasing reaction with the energy-requiring one to carry out

Reaction coupling to create glucose-6-phosphate - Khan Academy

https://www.khanacademy.org/science/ap-biology/cellular-energetics/cellular-energy/v/reaction-coupling-to-create-glucose-6-phosphate
Reaction coupling is a process in which two reactions are linked together, with one providing the energy needed for the other to occur. In coupled reactions, an energetically favorable reaction (exergonic) releases energy, which is then used to drive an energetically unfavorable reaction (endergonic). This allows the overall coupled reaction to

Unfavorable reactions occur when they are coupled to thermodynamically favorable reactions. This requires that the two reactions share a common intermediate. In this example the two reactions share the component "D". Let us assume that the upper reaction is unfavorable while the lower reaction is favorable.

Cell - Coupled Reactions, Metabolism, Enzymes | Britannica

https://www.britannica.com/science/cell-biology/Coupled-chemical-reactions
Cell - Coupled Reactions, Metabolism, Enzymes: Cells must obey the laws of chemistry and thermodynamics. When two molecules react with each other inside a cell, their atoms are rearranged, forming different molecules as reaction products and releasing or consuming energy in the process. Overall, chemical reactions occur only in one direction; that is, the final reaction product molecules

The most common coupled reactions occur in biochemistry. Every second, your body's cells use thousands of coupled reactions. Cells generate chemical change by converting adenosine triphosphate (ATP) to adenosine diphosphate (ADP). Glucose is the source of carbohydrate fuel in cells. The mitochondria can convert one mole of glucose into 36 moles

https://bio.libretexts.org/Bookshelves/Biochemistry/Book%3A_Biochemistry_Free_and_Easy_(Ahern_and_Rajagopal)/02%3A_Energy/2.03%3A_Energy_Coupling
The energy needed to drive reactions is harvested in very controlled conditions in the confines of an enzyme. This involves a process called 'coupling'. In coupled reactions, an enzyme binds both a high energy molecule (usually ATP) and the other molecule (s) involved in the reaction. Hydrolysis of ATP provides energy for the enzyme to

Reaction 1 in isolation produces relatively little copper or sulfur, but it is dragged toward the products by reaction 2, a favorable reaction that removes sulfur from the system. If we assume that there are no other reactions occurring within the system, we can calculate the \(\Delta \mathrm{G}^{\circ}\) for the coupled reactions 1 and 2.
