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+].

Which of the following statements about enzymes are true? Select all that apply: Enzymes increase reaction rates by lowering the energy of the products. Enzymes increase the rate at which products are created by preventing reactions from running backwards. Enzymes increase reaction rates by lowering the activation energy of a reaction. Enzymes increase reaction rates by interacting with the substrate molecules to facilitate the reaction, for example by contorting them to facilitate bond-breakage or orienting them to favor bond formation.
