Anaerobic Cellular Respiration

Anaerobic Cellular Respiration

Anaerobic Cellular Respiration

• 2 Types-- Alcoholic and Lactic Acid

• NO Oxygen required

• Occurs after Glycolysis in the cytoplasm if no oxygen is present

• No ATP is made after glycolysis

Multiple Select

oxygen

• mitochondria

• chloroplast

• cytoplasm

• cell membrane

Multiple Select

What is the net ATP after fermentation?

• none

• 32

• 36

• 2 from glycolysis

Alcoholic Fermentation

• Occurs in plants and yeast

• produces ethyl alcohol and CO₂

• Examples-- Used to make beer and wine and to make bread rise

Multiple Select

What kinds of organisms can go through alcoholic fermentation?

• plants

• animals

• yeast

• bacteria

Multiple Select

What are the products of alcoholic fermentation?

• O₂

• ethyl alcohol

• CO₂

• C₆H₁₂O₆

Lactic Acid Fermentation

• Occurs in animals

• produces lactic acid

• lactic acid fermentation by microorganisms plays an essential role in manufacturing foods like yogurt and cheese

Lactic Acid in Muscles

• When muscles run out of oxygen during exercise, the cells switch to lactic acid fermentation to get the energy needed

• side effects of lactic acid build up include muscle fatigue, pain, cramps, and soreness

Multiple Select

What kinds of organisms can go through lactic acid fermentation?

• animals

• plants

• yeast

• bacteria

Multiple Select

What are the product(s) of lactic acid fermentation?

• ethyl alcohol

• CO₂

• O₂

• lactic acid
