Chemical equilibrium is relatively rare in living cells.Which of the following could be an example of a reaction at chemical equilibrium in a cell?
A)a reaction in which the free energy at equilibrium is higher than the energy content at any point away from equilibrium B)a chemical reaction in which the entropy change in the reaction is just balanced by an opposite entropy change in the cell's surroundings C)an endergonic reaction in an active metabolic pathway where the energy for that reaction is supplied only by heat from the environment D)a chemical reaction in which both the reactants and products are not being produced or used in any active metabolic pathway E)no possibility of having chemical equilibrium in any living cell
Which of the following shows the correct changes in thermodynamic properties for a chemical reaction in which amino acids are linked to form a protein?
Which of the following is (are)true for anabolic pathways?
A)They do not depend on enzymes. B)They are usually highly spontaneous chemical reactions. C)They consume energy to build up polymers from monomers. D)They release energy as they degrade polymers to monomers. E)They consume energy to decrease the entropy of the organism and its environment.
