What happens to intracellular hydrogen ion concentration when extracellular pH drops (acidemia), if buffers and cellular mechanisms cannot fully compensate?
Show answer and explanation
Correct answer: Intracellular pH falls, impairing enzymes
A drop in extracellular pH increases extracellular H⁺; if buffering is overwhelmed, H⁺ enters cells, lowering intracellular pH and potentially disrupting enzyme activity and cellular function.
