Answer All
26. Which statement is false? (a) The endo (b) Rough Esmie reticulum (ER) is connected to the nuclear membrane. (c) Proteins t rough because of folds in the membrane that increase surface area. (d) Proteins alated (i.e., polysaccharides are added) in the Golgi apparatus. (ay Proteins are moved from the ER to t ER to the Golgi via vesicles. membrane protein is synthesized by: (a) ribosomes on the ER. (b) ribosomes in the cytoplasm. (c) lysosomes. (d) peroxisomes molecules of ATP are hydrolvzed to ADP and P, in a test tube, about twice as mu ch heat is released as a cell hydrolyzes the same amount of ATP. Which of the following is thwhe is the bes t explanation for this observation? (a) Cells are open systems, but a test tube is a closed system. (b) Cells are less efficient at heat production than nonliving systems. (o) The reaction in cells must be catalyzed by enzymes, but the reaction in a test tube does not need enzymes. (d) Cells convert some of the energy of ATP hydrolysis into other forms of energy besides heat. 29. Which statement is false? (a) Microtubules can be described as a hollow pipe. (b) The monomer that makes up microtubules is called keratin. (c) The monomer that makes up microfilaments is called actin. (d) Centrosomes contain microtubules in a 9x3 arrangement. 30. Cells can interact with the extracellular matrix (ECM) via: (a) Cell surface proteins such as integrins (b) Cytoskeletal elements such as microfilaments (c) Cytoskeletal elements such as microtubules (d) Transport vesicles 31. Plant cells that are next to each other can communicate via plasmodesmata. What type of cell junction is used for communication between animal cells? (a) Desmosomes (c) Gap junctions (d) Collagens (b) Tight junctions
