16. Which statements are correct regarding both fermentation and anaerobic respiration? Mark all that apply. The ATP yield is lower for both processes than for aerobic respiration. Both processes regenerate NAD+ to enable ATP production during glycolysis Microbes using these processes tend to grow at a slower rate than aerobic microbes The final electron acceptor for both is a molecule other than oxygen Bacteria known to be obligate aerobes are grown in the presence of atmospheric oxygen in broth containing glucose. Gas bubbles are observed in the test tube. What is most likely the gas that is being produced? nitrogen axygen carbon dioxide hydrogen.
