Cells and Endomembrane

1. a protein with one or more convalently attached carbohydrates
5. a type of motor protein that associates into filaments that interact with actin filaments to cause cell contraction
7. a type of endocytosis in which large particulate substances or small organisms are taken up by a cell.
9. an optical instrument with lenses that refract visible light to magnify images of specimens
10. (euk cell) double membrane that surrounds the nucleus, perforated with pores that regulate traffic with the cytoplasm
12. a hollow rod composed of tubulin proteins that makes up part of the cytoskeleton in all eukaryotic cells and is found in cilia and flagella

2. an organelle containing enzymes that transfer hydrogen atoms from various substrates to oxygen
3. a protein that interacts with cytoskeletal elements and other cell components, producing movement of the whole cell or parts of the cell
4. in animal cells, a transmembrane receptor protein with two subunits that interconnects the extracellular matrix and the cytoskeleton
6. a membrane-enclosed sac of hydrolytic enzymes found in the cytoplasm of animal cells and some protists
8. A type of intercellular junction in animal cells, consisting of proteins surrounding a pore that allows the passage of materials between cells.
11. a stack of membrane-bounded thylakoids in the chloroplast. Grana function in the light reactions of photosynthesis
