Q1. Yeast cells undergoing alcoholic fermentation produce ethanol. Which intermediate molecule is formed immediately after the decarboxylation of pyruvate?
Answer: Acetaldehyde
Explanation: Pyruvate is decarboxylated to acetaldehyde first; lactic acid fermentation is different because it involves no decarboxylation or CO2 release.
