Energy Release and Conservation 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 The process generates oxygen, which is required for glycolysis Ethanol keeps the electron transport system functioning The process regenerates NAD+, which is required for glycolysis Yeast would be unable to activate the enzymes of the Krebs cycle without ethanol The process generates oxygen, which is required for glycolysis Ethanol keeps the electron transport system functioning The process regenerates NAD+, which is required for glycolysis ANSWER DOWNLOAD EXAMIANS APP
