Flashcards in Ultrastructure Deck (34):
1

cell membrane is aka

plasmalemma/plasma membrane

2

layout of cell membrane is blank

trilaminar (dark light dark)

3

blank chromatin is dark

hetero

4

blank chromatin is light

eu

5

euchromatin areas are involved in blank

active transcription

6

smallest part of cells

ribosomes

7

polyribosomes are tied together by blank

mRNA

8

size of ribosomes

20 nm

9

clusters of glycogen

alpha

10

alpha glycogens are aka

rosettes

11

alpha glycogens have a blank surrounding them

halo

12

beyond the halo, glycogen will have blank surrounding it

SER

13

beta glycogen is in these muscles

skeletal, cardia

14

alpha glycogen is usually in blank

liver

15

ribosomes are attached on the blank side of RER

cytoplasmic

16

polyribosomes organize into this shape

swirl

17

this is when the RER makes a bunch of protein and there is a backup

bloated cistern

18

does RER have a membrane?

yes

19

profiles of SER tend to be blank in shape and size

irregular

20

SER is involved in neutralization of blank

drugs

21

golgi body folds toward the blank face and gets smaller than at the blank face that receives protein from RER

maturing, forming

22

inside maturing face of golgi bodies, blank are found

proteins in transfer vesicles

23

golgi is sometimes located near the blank

nucleus

24

because of two faces, golgi is considered blank

polarized

25

dense bodies vesicles

primary lysosomes

26

there are pigments and residual bodies in blank

secondary lysosomes

27

two pathways of lysosomes

heterophagic, autophagic

28

primary lysosomes are blank stained

uniiiformly

29

secondary lysosomes are blank stained

unevenly

30

primary lysosome are in the blank stage

inactive

31

secondary lysosomes are in the blank stage

active

32

allows movement of particles in the cell, movement of the cell itself, structure of the cell

cytoskeleton

33

microfilament, intermediate, microtubule sizes

5-7, 10-15, 24 (nm)

34

dark areas of electron microscopy

electron dense
