Although glycolysis requires an input of ATP, this pathway results in a net gain of two ATP; therefore it is a(n) ________ pathway.
A) exergonic
B) endergonic
C) oxidative
D) reductive
E) neither exergonic nor endergonic

Question

Quizplus · Accepted Answer

Glycolysis is an exergonic pathway as it releases energy in the form of ATP. Although two ATP molecules are used in the initial steps of glycolysis, four ATP molecules are produced via substrate-level phosphorylation, resulting in a net gain of two ATP molecules.
