Question
Chapter 16, Problem 60P
Interpretation Introduction
Interpretation:
The reason for the formation of lactate in the cells should be determined.
Concept introduction:
Fermentation is the process in which pyruvate is fermented to lactic acid or alcohol. Lactic acid is formed in the lactic acid fermentation process, and alcohol is formed in the alcohol fermentation process. Pyruvate is the end-product of glycolysis process.
