Both start with glycolysis.
Explanation: Both pathways begin by breaking glucose into pyruvate via glycolysis (in the cytoplasm), producing a small net ATP and NADH. After glycolysis they diverge: alcohol fermentation regenerates NAD+ by converting pyruvate to ethanol + CO2 (no O2 needed), while aerobic respiration uses O2 as the final electron acceptor in the Krebs cycle and oxidative phosphorylation, producing much more ATP and CO2 + H2O.
