36. what metabolic pathway is depicted below?
pyruvic acid
co2 + acetaldehyde
acetaldehyde
ethanol
nadh nad

Anaerobic respiration or fermentation

Explanation:

The metabolic pathway shown in the question is the summary of anaerobic respiration (fermentation) during which pyruvate is converted to acetaldehyde, followed by the formation of alcohol (ethanol), along with the release of NADH and NAD molecules. This mechanism occurs in the absence of oxygen and is thus used by organisms to generate energy (ATP) molecules.
