Question

The Cell 29- In which cellular compartment is the location in which macromolecules are degraded by A. Smooth ER B. Peroxisome C. Lysosome E. Golgi 30- What are the structures that synthesize proteins in the cytoplasm? A. Ribosome B. vacuole D. Peroxisome 31-Lysosomes contain hydrolytic enzymes that are activated by increasing the concentration of hydrogen ions. Even before the lysosome begins to increase the concentration of hydrogen ions, there is a higher concentration of hydrogen ions inside of the lysosome than in the cytoplasm. Thus, this structure lowers its pH by a process known as: osis B. Active transport C. Facilitated diffusion D. Simple diffusion E. Exocytosis 32- Which of the following is true concerning eukaryotes and prokaryotes? A. P Prokaryotic cells have cell walls; eukaryotic cells do not have cell walls. B. Prokaryotic don't have membrane-bound structures, eukaryotes cells do have membrane bound structures. C. Prokaryotic don't have ribosomes; eukaryotes do have ribosomes. D. Prokaryotes have a nucleic region; eukaryotes have a nucleus.
