Answer:
1. Forms fewer ATP molecules and cellular respiration
Step-by-step explanation:
Alcohol fermentation is usually done by yeast as us humans lack the genetic information to do it (however we can do lactic acid fermentation in low Oxygen level which produce Lactic acid, which is what hurts after a day or two of heavy playing or workout)
Alcohol Fermentation only produces two ATP which is significantly lower than what cellular respiration makes (scientists predict there to be about 38 ATP from per cycle of respiration)
