6. In a DNA molecule, the phosphate serves A) as a code to hold the molecular backbone together C) to bind the sugars to their bases D) as nucleotides E) to connect nitrogenous bases to the deoxyribose sugar 7. In certain kinds of muscle cells, calcium ions are stored in the smooth ER B) the rough ER C) both smooth and rough ER D) inclusions E) the cytoplasm 8. Certain cells of the pancreas are specialized to synthesize and release digestive enzymes. Knowing this, what organelles would you expect to be particularly abundant/large? Choose ALL that are correct (i.e., bubble in every correct letter on your scantron). A) DNA Golgi apparatus Rough ER Smooth ER E) Lysosomes 9. Which of the following is not a factor that binds cells together? A) glycoproteins in the glycocalyx B) glycolipids in the glycocalyx C) wavy contours of the membranes of adjacent cells gap junctions E) desmosomes 10. Ribosomes, rough endoplasmic reticulum, and the Golgi apparatus functionally act in sequence to synthesize and modify proteins for secretory use (export) only, never for use by the cell. This statement is A) false; proteins thus manufactured are for use inside the cell only B false; integral cell membrane proteins are also synthesized this way C) false; lipids, not proteins, are synthesized this way D) false; ribosomes synthesize carbohydrates E) true 6.
