3. 

Reactions that have positive standard free energy changes (ΔGo> 0) can be made to occur in cells by

[A]. coupling them with exergonic reactions via a common intermediate
[B]. manipulating the concentrations of products and reactants such that G/<0
[C]. coupling them to the hydrolysis of ATP
[D]. all of the above

Answer: Option D

Explanation:

No answer description available for this question.

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.

Because ΔG° do not determine the reaction is endorganic or exorganic.
