Which of the following best explains about the usefulness of the production of ethanol in yeast cells under anaerobic conditions?

Yeast would be unable to activate the enzymes of the Krebs cycle without ethanol

Ethanol keeps the electron transport system functioning

The process regenerates NAD+, which is required for glycolysis

The process generates oxygen, which is required for glycolysis
