Flashcards in Chapter 5: Eukaryotic Cells Deck (18):
1

-nucleus is separated from the cytoplasm by this
-consists of two membranes

nuclear envelope (nuclear membrane)

2

embedded in the nuclear envelope regulate the transport of proteins and RNA molecules between the nucleus and cytoplasm

nuclear pore complexes

3

liquid within the nucleus is called....?

nucleoplasm

4

formed around the genes coding for rRNA molecules of ribosomes

nucleoi

5

divides the cell into functional and structural compartments

endomembrane system

6

small membrane-bound sacs that transfer substances between parts of the system

vesicles

7

carries out various functions through several types of embedded proteins

plasma membrane

8

extensive interconnected network (reticulum) of membranous channels and cisternae

endoplasmic reticulum (ER)

9

each cisternae is formed by a single membrane that surrounds an enclosed space

ER lumen

10

has many ribosomes o nits outer surface

rough ER

11

proteins to be secreted from the cell are transported to the membrane in _____ which release their contents to the exterior by exocytosis

secretory vesicles

12

-no ribosomes attached to their surfaces
-synthesizes lipids that become part of cell membranes

smooth ER

13

constists of a stack of flattened, membranous sacs (cisternae)

golgi complex

14

small, membrane-bound vesicles contining hydrolytic enzymes that digest complex molecules

lysosomes

15

membrane-bound organelles that have their own DNA, in which cellular respiration occurs

mitochondria

16

mitochondria have two membranes surrounding an inner compartment

mitochondrial matrix

17

covers the organelle

outer mitochondrial membrane

18

expanded by folds called cristae

inner mitochondrial membrane
