Questions and Answers
What is lactic acid fermentation?
The conversion of pyruvic acid that forms as a result of glycolysis into lactic acid, which regenerates NAD so that glycolysis can continue.
What is the lactic fermentation equation?
pyruvic acid + NADH ----> lactic acid + NAD+
When is lactic acid produced in the muscles?
During rapid exercise when the body cannot supply enough oxygen to the tissues.
The lack of oxygen allows the body to produce all of the required ATP.

Study Notes
Lactic Acid Fermentation
- Converts pyruvic acid, resulting from glycolysis, into lactic acid.
- Regenerates NAD+, which is essential for glycolysis to continue.
Lactic Fermentation Equation
- The reaction involves pyruvic acid and NADH producing lactic acid and NAD+.
Production of Lactic Acid
- During rapid exercise, lactic acid accumulates in muscles due to insufficient oxygen supply.
- This process occurs when the energy demands exceed oxygen availability.
Lack of Oxygen
- Insufficient oxygen limits ATP production, leading to anaerobic conditions in muscles.
- Cells rely on alternative energy pathways, such as lactic acid fermentation, under low oxygen.
Lactic Acid and ATP Production
- In low oxygen conditions, muscles produce ATP via lactic acid fermentation to sustain energy levels.
