Question
Which structure is the site of the synthesis of proteins that may be exported from the cell? A) rough ER B) lysosomes C) Plasmodesmata D) Golgi vesicles E) free cytoplasmic ribosomes the Golgi apparatus has a polarity of sidedness to its structure and function. Which of the following statements correctly describes this polarity? A) Transport vesicles fuse with one side of the Golgi and leave from the opposite side. B) Proteins in membrane of the Golgi may be sorted and modified as they move from one side of the Golgi to the other. C) Lipids in the membrane of the Golgi may be sorted and modified as they move from one side of the Golgi to the other. D) Soluble proteins in the cisternae (interior) of the Golgi may be sorted and modified as they move from one side of the Golgi to the other. E) All of the above correctly describe polar characteristics of the Golgi function. Hydrolytic enzymes must be segregated and packaged to prevent general destruction of cellular components. Which of the following organelles contains these hydrolytic enzymes in animal cells? A) chloroplast B) lysosome B) vacuole C) mitochondrion D) Golgi apparatus E) peroxisome Which of the following statements about the cytoskeleton is true? A) The dynamic aspect of cytoskeletal function is made possible by the assembly and disassembly of a large variety of proteins into complex aggregates. B) Microfilaments are structurally rigid and resist compression, whereas microtubules resist tension (stretching). C) Movement of cilia and flagella is the result of motor proteins causing microtubules toExplanation / Answer
