Flashcards in Organelles etc Deck (57):
1

everything besides the nucleus

cytoplasm

2

fluid only

cytosol

3

fluid of the nucleus

nucleoplasm

4

membrane around the nucleus, regulates what goes in and out

nuclear envelope

5

channel proteins

nuclear pores

6

synthesis of ribosomal rna

nucleolus

7

3 kinds of protein sorting

across nuclear pores, directly across organelles, transport by vesicles

8

person w signal sequences

gunter blobel

9

synthesis of all lipids, want more surface area

smooth er

10

start of protein modification

rough er

11

final modification, leave through vesicle

golgi

12

special enzymes, organizes things coming in

endosome

13

hydrolytic enzymes

lysosome

14

oxidation of toxic molecules

peroxisomes

15

apoptosis and energy production

mitochondria

16

have own dna and ribosomes

mitochondria

17

inner membrane is where photosynthesis takes place

chloroplast

18

connections that hold cells together

cellular junctions

19

lysosome breaking down dead/ dying organisms

autophagy

20

protein modification examples

specialized, glycoproteins

21

organizes/ stores chromosomes

30

H+ pump

hydrogen ions into lysosome, active transport (greater to lesser)

31

3 types of filaments

actin, intermediate, microtubules

32

int: protein

various proteins

33

int size

10nm

34

int locations

cytoplasm, nucleus

35

int function

strength and support

36

actin protein

actin

37

polymerization depolymerizations

bind and form filaments controlled by ATP AND ADP

38

actin size

7 nm

39

actin location

cortex of cytoplasm

40

actin function(s)

1) make microvilli - to inc surface area
2) muscle contraction
3) endocytosis
4) cytokinesis

41

micr protein

tubulin

42

polymerization (microtubules)

form filaments, GTP AND GDP

43

micr size

25 nm diameter

44

micr location

cytoplasm

45

micr center for organizing

centrosome

46

micr functions

1) transportation of vesicles and organelles
2) mitotic spindle
3) cilia and flagella

47

dynein and kinesin are used for

carrying vesicles across microtubules

48

what makes pos/neg ends of micr

amino and carbolxyl ends

49

why make microvilli

to increase surface area (absorb more nutrients)

50

how do muscles contract

filaments slide and muscle cells shorten

51

endocytosis with filaments

wrap membrane, they depolymerize to pull in and create a vesicle

52

actin fcn cytokinesis

divide cytoplasm

53

type of junction that attaches actin on one cell to actin on another

adherens

54

type of junction that joins intermediate filaments in one cell to another

desmosome

55

type of junction responsible for flow of ions

gap junction

56

type of junction that anchors int filaments to basal surfaces

hemidesmosome

57

type of junction that seals neighboring cells to prevent leakage

tight junction
