In a typical cell, why are non-thermodynamically favorable reactions possible?
In a typical cell, non-thermodynamically favourable reactions are possible because those reactions are coupled with ATP hydrolysis. ATP is the energy currency of the cell. The breakdown of ATP into ADP releases energy and it can be used to carry non thermodynamically favourable reaction.
In a typical cell, why are non-thermodynamically favorable reactions possible?
All exothermic reactions are favorable. Using your own words, explain why some exothermic reactions are non-spontaneous even when they are all favorable. HTML Editor
1. In a cell, a thermodynamically unfavorable process can occur if the process is coupled to a thermodynamically favorable process. the process is thermodynamically favorable outside the cell. an enzyme gives energy to the reacting substances. the cell as a whole is close to equilibrium. 2. In an active transport protein, ATP hydrolysis creates a channel through the membrane. ATP uses the protein to move across the membrane. ATP hydrolysis causes the protein to change shape. ATP carries a substance...

Why does base stacking cause energetically favorable reactions in DNA?
In a quiz I got a reaction, not thermodynamically favorable: Cu₂S → 2Cu(s) + S(s) ∆G° = + 86kJ/mol The question said: 'We can force this to happen by using a battery'.. (i) Using ∆G°, calculate E°cell .... They then gave the reduction potential of Cu, and put the reduction reaction of sulfur with unknown reduction potential Cu2+ + 2e- → Cu E° = 0.34 S + 2e- → S2- E°= ??? (ii) Using your answer in part (i), calculate...

hemical Thermodynamics Coupled Reactions Resources « previous| 10 of 13 next >» Coupled Reactions Part A Consider these hypothetical chemical reactions In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions that are thermodynamically favorable. As long as the overall reaction is thermodynamically favorable even the unfavorable reaction will proceed 1. A-B, 2.B-C, 3, C D, ΔG= 13.0 kJ/mol ΔG=-26.2 kJ/mol ΔG= 7.70 kJ/mol What is the free energy, ΔG, for...
