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...

Question 4 30 pts How can a metabolic pathway contain an energetically unfavorable reaction yet still occur? The free-energy changes of the individual steps in a pathway are summed to determine the overall free-energy change. [Choose] TRUE FALSE [Choose] A step in a pathway that is energetically unfavorable can be driven by coupling it to a thermodynamically favorable reaction. [Choose ] At equilibrium, very few "energetically unfavored" products might be present - but if these unfavored products are then being...

Review Constants Periodic Table When conducting chemical reactions in the lab or in industrial processes, can be important to know whether a reaction has reached equilibrium. By measuring the reaction quotient, Q. of a chemical reaction and comparing it to the equilibrium constant, K. we can identity whether a reaction is at equilibrium ✓ Correct Q is less than K. the ratio of products to reactants is smaller than at equilibrium. In this case, the reaction wil proceed to the...
