Question

Of the following organelles, which group is involved in manufacturing substances needed by the cell? a. lysosome, vacuole, ribosome b. ribosome, rough ER, smooth ER c. vacuole, rough ER, smooth ER d. smooth ER, ribosome, vacuole e. rough ER, lysosome, vacuole 2. Which of the following is NOT a characteristic of prokaryotes? a. DNA b. cell membrane c. cell wall d. endoplasmic reticulum 3. Proteins synthesized by the rough ER are: a. for internal storage in the Golgi Apparatus b. to build more membranes in the cell c. to digest food in lysosomes d. for internal regulation e. exported from the cell 4. Which of the following describes the fluid-mosaic model of the plasma membrane structure? a. phospholipid monolayer with embedded proteins b. phospholipid bilayer with embedded proteins c. phospholipid trilayer with embedded proteins d. triglyceride bilayer with embedded proteins e. triglyceride monolayer with embedded proteins 5. True (a) or False (b): Metabolism is a complex chemical process accomplished in an organism by which large molecules are destroyed and small ones are produced. At the end of this process, composed of 2 different kinds of reactions (catabolism and anabolism), energy is produced and released by cells.
