A thermodynamically unfavorable reaction can become favorable when coupled to a highly ________ reaction.
A thermodynamically unfavorable reaction can become favorable when coupled to a highly ________ reaction.
Homework Answers
A thermodynamically unfavorable reaction is a non sponataneous, endothermic reaction in which the free energy is positive. This reaction absorbs energy.
A unfavorable reaction can become favourable by coupling it with a favorable reaction.
A thermodynamically favorable reaction is an exothermic reaction and spontaneous. This reaction releases energy.
Therefore, the correct solution is thermodynamically favorable.

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...
