An energetically unfavorable reaction can proceed if it is coupled to an energetically favorable reaction. How does this happen?A) This statement is false; energetically unfavorable reactions will never proceed. B) Enzymes can alter the free energy change of reactions, so the reaction is no longer unfavorable. C) The individual free energy changes of sequential reactions are additive, yielding an overall free energy change for the coupled reaction.

Osmosis is often viewed incorrectly as a process driven directly by differences in solute concentration across a selectively permeable membrane. what really drives osmosis? view available hint(s)osmosis is often viewed incorrectly as a process driven directly by differences in solute concentration across a selectively permeable membrane. what really drives osmosis? the first law of thermodynamicsthe difference in the height of water columns on either side of a selectively permeable membranethe difference in water concentration across a selectively permeable membranethe difference in sugar or ion concentration across a selectively permeable membrane

Plz ! ive been stuck on this forever
