← Nature & AnimalsWhich critical restriction emerges due to inefficiencies in lungfish air-breathing oxygen uptake under high-activity periods?
A)Enhanced anaerobic metabolic lactic acidosis✓
B)Decreased reliance circulatory oxygen transport
C)Increased reliance skin oxygen exchange
D)Greater efficiency chloride cell ionoregularity
💡 Explanation
During strenuous activity, lungfish oxygen demand surpasses branchial oxygen uptake; thus, a surge toward anaerobic metabolism leads to lactic acidosis, because oxidative phosphorylation cannot meet demands, therefore metabolic acidosis rather than ionic regularities or skin exchange increases.
