Question

you are given a solution in which a biochemical reaction is occurring, and you are unsure whether δg is positive or negative. you suspect that the reaction might make use of the atp to adp + pᵢ energy - coupling system. to test whether it uses this system, and to determine whether the reaction is exergonic or endergonic, you would add _. if the reaction _, you would conclude that it is _. o atp; lit up; exergonic o atp; produced a decrease in temperature; exergonic o adp; made more product; exergonic o atp; made more product; endergonic o adp; made phosphate ions; endergonic

Explanation:

Exergonic reactions release energy and can be coupled with the hydrolysis of ATP (ATP to ADP + Pi). Adding ATP to a reaction and seeing more product formation indicates that the reaction is using the energy from ATP hydrolysis, suggesting it is endergonic (requires energy input). If adding ATP leads to more product, it means the reaction needs the energy provided by ATP, which is characteristic of an endergonic reaction.

Answer:

ATP; made more product; endergonic
