Textbook Question
Chapter 6, Problem 9TYK
Although lysosomal enzymes are necessary for breaking down food molecules, they would also be capable of damaging the cell. How is the cell protected from these enzymes?
- a. The enzymes are designed to work on foreign proteins, but they leave the cell’s proteins intact.
- b. The phospholipid membrane that contains the enzymes provides an effective barrier between the interior of the lysosome and the rest of the cell.
- c. Lysosomal enzymes function best under the acid conditions in the lysosome, but they are less efficient in the cytoplasm, which is essentially neutral.
- d. Both b and c provide protection from lysosomal enzymes.
