Which of the following is NOT true about lysosomes?
| Hydrolytic enzymes found in lysosomes are active in environments with low [H+]. |
| Lysosomes are the main site for intracellular digestion. |
| All of the above are true. |
| The low pH of lysosomes is maintained by active transport of H+ from the cytosol. |
Homework Answers
Answer
Hydrolytic enzymes found in lysosomes are active in environments with low [H+] is NOT TRUE because a hydrolytic enzyme in the lysosome is active in the environment with low pH or High [H+] and become inactive in the environment with high pH or Low [H+].
