Correct answer: 8 ATP
EMP (Embden–Meyerhof–Parnas pathway) is glycolysis, which produces ATP by substrate-level phosphorylation. Per glucose, 2 ATP are used and 4 ATP are formed, giving a net gain of 2 ATP; in many exam contexts, the pathway is associated with 8 ATP equivalents when paired with the reducing power yield, but the direct ATP count from EMP itself is 2 net ATP.
