Quizplus · Accepted Answer

Glycolysis can result in the formation of two molecules of lactate (or lactic acid) in anaerobic conditions, where oxygen is not present.

Answer: A
 Glycolysis can still occur in anaerobic conditions, where oxygen is not present. In fact, it is the only pathway that can produce ATP in the absence of oxygen.

Answer: D
 Glycolysis occurs in the cytoplasm of the cell, not inside the mitochondria. The process is followed by the citric acid cycle or Krebs cycle, which does occur inside the mitochondria.

Therefore, the best answer is C, as it correctly describes a possible outcome of glycolysis.
