A young animal has never had much energy. He is brought to a veterinarian for help and is sent to the animal hospital for some tests. There they discover his mitochondria can use only fatty acids and amino acids for respiration, and his cells produce more lactate than normal. Of the following, which is the best explanation of his condition?

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.
