Aerobic vs Anaerobic Respiration Lactic Acid & Alcohol Fermentation

Aerobic Respiration Requires oxygen to create ATP energy Main way that food is converted into usable energy Takes place in the mitochondria Very efficient 1 glucose molecule produces 32-36 ATP molecules

Anaerobic Respiration Doesn’t require oxygen to produce ATP Another way food is converted into energy Takes place in the cytoplasm Prokaryotes Cheese, yogurt, sour cream, and pickles Animals use this process when muscle cells are overworked over a short period of time. (Exercising) Fermentation Organisms living in low-oxygenated environments No mitochondria

Lactic Acid Fermentation Animals and bacteria For short bursts of energy, exercising Converts glucose into 2ATP + Lactic Acid https://www.youtube.com/watch?v=Ybdk bCU20_M

Alcohol Fermentation Yeast and other microorganisms Converts glucose into alcohol + CO2 + 2ATP Causes bread to rise Produces alcoholic beverages Both types of fermentation only produce 2ATP molecules for every 1 molecule of glucose.
