A reaction has ΔG < 0. This means it
A.is exergonic and releases energy
B.is endergonic and requires energy
C.cannot occur without an enzyme
D.violates thermodynamics
Explanation
Core Concept
Negative ΔG marks spontaneous, energy-releasing reactions — catabolic steps like ATP hydrolysis. Positive ΔG reactions need energy input.
Correct Answer
Ais exergonic and releases energy
