Muscle cells use lactic acid fermentation toMultiple Choiceregenerate NAD+ so that glycolysis can continue in the absence of oxygen.produce ATP in the presence of oxygen.produce more ATP than in respiration.allow an animal to survive for long periods of time in the absence of oxygen.produce less CO2.

Cells produce a small amount of ATP and lactic acid in the absence of oxygen through the process of respiration.

Fermentation:Group of answer choicesDoes not require oxygen.Produces less ATP than aerobic respiration.Uses an organic molecule as the final electron acceptor.Releases energy from sugars or other organic molecules.All of the above.Next

Of the three pathways for obtaining ATP for muscle contraction, which one requires oxygen?Multiple Choiceonly the creatine phosphate pathwayonly fermentationonly respirationfermentation and respirationthe creatine phosphate pathway and fermentation

Why is pyruvate converted to lactate in anaerobic conditions?Multiple ChoiceTo regenerate NAD+NAD+ from NADH and keep glycolysis functioning.To regenerate NADH from NAD+NAD+ and keep glycolysis functioning.To produce more oxygen to allow the electron transport chain to resume.The conversion of pyruvate to lactate also produces ATP which keeps the cell alive.The conversion of pyruvate to lactate requires ATP and is thus exergonic.

Which makes ATP from glucose without oxygen?Group of answer choicesaerobic respirationanaerobic respiration
