← Nature & AnimalsWhich risk accelerates when ram ventilation effectiveness reduces while swimming in a fish adapted to hypoxic conditions?
A)Increased lactic acid accumulation✓
B)Elevated sodium ion excretion
C)Depletion of liver glycogen stores
D)Reduced opercular beat frequency
💡 Explanation
When ram ventilation reduces, the efficiency of countercurrent gas exchange in the gills decreases because less oxygenated water flows against the blood. This leads to anaerobic respiration, increasing lactic acid production. Therefore, lactic acid accumulation accelerates, rather than changes in ion balance, glycogen stores, or gill movement which are linked to distinct metabolic pathways.
