It might seem odd that we have an enzyme in our bodies that catalyzes a "reversible reaction"; one that goes either forward or backward, depending on the relative concentrations of reactants. What's the point of that? How is it that the enzyme is helpful to an organism in that case?

It might seem odd that we have an enzyme in our bodies that catalyzes a "reversible reaction"; one that  goes either forward or backward, depending on the relative concentrations of reactants. What's the point of that? How is it that the enzyme is helpful to an organism in that case?

danjs · Answer

the body probably needs certain concentrations of whatever those things are, and the catalyst enzyme may keep it near that equilibrium value..

It may be easier and a different rate to change from A to B, than B to A

danjs · Answer

the equilibrium should have a equal rate of change of A to B and of B to A

danjs · Answer

if one direction of the reaction happens readily and fast,  but the reverse reaction takes much longer or requires other factors or something, then the enzyme may be the thing to help equalize this to some value that the body requires..

idk , might be all wrong, just guesing
