QUESTION 17 How do proteins get sent to the chloroplast? they don't. Chloroplasts have their own genomes and ribosomes, so they produce all their own proteins. endomembrane trafficking cytoplasmic trafficking receptor-mediated endocytosis QUESTION 18 How do proteins enter the chloroplast? nuclear export sequence Tic/Toc complex nuclear localization sequence Dicer pathway QUESTION 19 Vesicles sorted by the Golgi that are targeted to the medial and trans-Golgi networks will be packaged into which type of vesicle? COP I Clathrin COP II QUESTION 20 Which is true of the distribution of the membrane protein Annexin V? it is evenly distributed in all membrane structures the amount varies in different cellular compartments/organelles it serves as a marker for apoptosis it is highly enriched in lipid rafts of the plasma membrane

20. Which organelle allows materials to move into and out of the cell? nucleus cell membrane chromosomes Lysosomes 21. This organelle is filled with digestive enzymes and helps break down old organelles: nucleus lysosome endoplasmic reticulum Ribosome 22. Which of the following is not found in plant cells? chloroplasts cell wall lysosomes large vacuole 23. Which organelle stores water, waste, and nutrients? ribosome endoplasmic reticulum centrioles Vacuole 24. The part of the cell membrane that is made of a polar head region and a non-polar tail region is called a phospholipid carbohydrate protein Nucleus 25. This part of the cell membrane provides channels or passageways for ions or molecules to move through: carbohydrates lipids protein nucleic acid
