Question:
The intracellular pH of human cells is approximately 7.4. Yet, the pH within the lumen (inside) of the human stomach averages 1.5. Which of the following accurately describes the difference between the acidity of the cellular and gastric pH?
(A) Gastric juices contain approximately 6 times more H+ ions than the intracellular cytoplasm of cells and are more acidic.
(B) Gastric juices contain approximately 1,000,000-fold more H+ ions than the intracellular cytoplasm of cells and are more acidic.
(C) The intracellular cytoplasm of cells contain approximately 6 times more H+ ions than gastric juices and is more acidic.
(D) The intracellular cytoplasm of cells contains approximately 1,000,000-fold more H+ ions than gastric juices and is more acidic.
