You have a friend who lost 7 kg (about 15 pounds) of fat on a regimen of strict diet and exercise. How did the fat leave her body?

Cellular respiration is a process that breaks down glucose to produce energy. Fermentation is a metabolic process that converts carbohydrates into acids or alcohols.  Here are some differences between cellular respiration and fermentation: Inputs: Cellular respiration uses glucose and oxygen as inputs. Fermentation uses carbohydrates as inputs. Outputs: Cellular respiration produces carbon dioxide, water, and energy (ATP) as outputs. Fermentation produces small, reduced organic molecules as waste. Complete oxidation: Cellular respiration completely oxidizes glucose into CO2 and water.... Show more

Cellular respiration is a process that breaks down glucose to produce energy. Fermentation is a metabolic process that converts carbohydrates into acids or alcohols. 

Here are some differences between cellular respiration and fermentation:
Inputs: Cellular respiration uses glucose and oxygen as inputs. Fermentation uses carbohydrates as inputs.
Outputs: Cellular respiration produces carbon dioxide, water, and energy (ATP) as outputs. Fermentation produces small, reduced organic molecules as waste.
Complete oxidation: Cellular respiration completely oxidizes glucose into CO2 and water. Fermentation does not fully oxidize glucose.
Energy release: Cellular respiration releases more energy from glucose than fermentation.
Oxygen: Cellular respiration uses oxygen. Fermentation can occur without oxygen.
