Anaerobic respiration provides lower energy.

In muscles, the chemical reactions occurs (glucose is oxidized):

#C_6H_12O_6 + 6O_2 -> 6CO_2 + 6H_2O + E#

Energy gained by this reaction is #2900 \ "kJ per mol"#.

In yeast, anaerobic repiration occurs:

#"Glucose"→"Pyruvic acid"→"ethanol + carbon dioxide + E"#

Energy gained by this reaction is #161 \ "kJ per mol"#.

Although the starting point (substance) is the same, anaerobic decay produces less energy compared to that happen in aerobic muscle respiration.
