Q1. When skeletal muscles undergo anaerobic respiration during intense exercise, which product is formed without the release of carbon dioxide?
Answer: Lactic acid
Explanation: Lactic acid fermentation produces no CO2, unlike alcoholic fermentation. Ethanol is tempting because it is a common fermentation product but involves decarboxylation.
