Explain explain that (HT only) lactic acid is converted back into glucose in the liver in the context of Respiration.

lactic acid is the starting point for this answer. (HT only) lactic acid is converted back into glucose in the liver. A clear answer should keep that idea linked to Response to exercise in Respiration. You can support the point by showing that a byproduct of anaerobic respiration in muscles, which can accumulate during intense exercise. Do not students often confuse the process of lactic acid being converted back into glucose with the process of glucose being broken down for energy; instead emphasize that lactic acid is converted back into glucose in the liver after exercise, and clarify that this is a separate process from glycolysis, which breaks down glucose for energy.

This question expects a structured explanation, not a single isolated fact. Credit comes from naming the correct idea, using precise biological vocabulary, and keeping the answer anchored to Response to exercise. Use make sure to explain the process of lactic acid being converted back into glucose in the liver during your exam answers. Link your answer to Response to exercise in Respiration, and keep the biology specific to lactic acid.
