p.667 top paragraph: "The secondary lysosomes, the main intracellular digestive compartment,
constitute the terminal compartment of the pathway. With a pH of 4.5-5.0, the
lysosomes are the most acidic organelles in animal cell (primary sources 43-45)." p.672 bottom line:"A number of laboratories have shown that in intact cells, the intralysosomal environment is maintained at a pH of 4.6-5.0 (primary sources 9, 35, 43, 44)." |
