| Question | Answer |
|---|---|
| In cilia and flagella, a large motor protein extending from 1 microtubule doublet to the adjacent doublet. ATP hydrolysis drives changes in its shape that lead to bending of cilia and flagella | dynein |
| a type of intercellular connection in animal cells, consisting of proteins surrounding a pore that allows the passage of materials between cells | gap junction |
| a non-membrane-bounded region in a prokaryotic cell where the DNA is concentrated. | nucleoid |
| the disruption of a cell and separation of its parts by centrifugation at successively higher speeds | cell fractionation |
| a type of motor protein that associates into filaments that interact with actin filaments to cause cell contraction | myosin |
| a structure present in the cytoplasm of animal cells that functions as a microtubule-organizing center and is important during cell division; has 2 centrioles | centrosome |
| a cable composed of actin proteins in the cytoplasm of almost every eukaryotic cell, making up part of the cytoskeleton and acting alone or with myosin to cause cell contraction; aka actin filament | microfilament |
| the portion of the ER with ribosomes attached | rough ER |
| the level of protein structure referring to the specific linear sequence of amino acids. | primary cell wall |
| a stack of membrane-bounded thylakoids in the chloroplast. Grana function in the light reactions of photosynthesis | granum |
| the contents of the cell bounded by the plasma membrane; in eukaryotes, the portion exclusive of the nucleus | cytoplasm |
| any of several membrane-enclosed structures with specialized functions, suspended in the cytosol of eukaryotic cell | organelle |
