Which Process Creates the Most ATP Per Glucose Molecule Metabolized

Question

Which process creates the most ATP per glucose molecule metabolized?
A) glycolysis
B) fermentation
C) anaerobic respiration
D) aerobic cellular respiration

Accepted Answer

Aerobic cellular respiration creates the most ATP per glucose molecule metabolized, with a net gain of 36-38 ATP molecules. Glycolysis only produces 2 ATP molecules per glucose molecule, fermentation produces only 2 ATP molecules per glucose molecule, and anaerobic respiration produces between 2-36 ATP molecules depending on the electron acceptor used.
