Even though our muscle cells contain mitochondria and normally undergo aerobic respiration, during
strenuous activity lactate is formed, which contributes to cramps in our muscles. What is the
evolutionary advantage of lactate production in our cells? What will be an ideal response?
Concepts to Consider: Although we are capable of aerobic respiration, anaerobic respiration can be
used as a backup system in case of low oxygen levels, as happens during strenuous activity; the
buildup of lactate contributes to cramps, which, in turn, causes us to slow our activity levels in order to
replenish oxygen levels.
