Thermodynamics and Free Energy
3.
Reactions that have positive standard free energy changes (ΔGo> 0) can be made to occur in cells by
coupling them with exergonic reactions via a common intermediate
manipulating the concentrations of products and reactants such that G/<0
coupling them to the hydrolysis of ATP
all of the above

Because ΔG° do not determine the reaction is endorganic or exorganic.
Suman dutta said:   10 years ago
Since del G is greater then 0 so reaction is endothermic. To proceed, a reaction must be exothermic that's why it is essential that either there must be involvement of ATP act as energy provider (point 3) OR there must be a reaction which must be exergonic.

That's why point 4 is correct.
