Q

Forms vesicles

A

Golgi Apparatus

25
Golgi Apparatus: cis face is?
Incoming proteins and lipids from the endoplasmic reticulum
26
Golgi Apparatus: trans face is?
departure of newly formed vesicles from the golgi apparatus
27
process that brings material into cell using vesicles
Endocytosis
28
occurs when a specific subtance binds to the receptor molecule
receptor-mediated endocytosis
29
“cell eating”
Phagocytosis
30
“cell drinking”
Pinocytosis
31
opposite of endocytosis and involves use of secretory vessels
Exocytosis
32
membrane-bound sacs are called ________
secretory vessels
33
membrane bound vesicles that contains variety of enzymes
Lysosomes
34
intracellular digestive systems
Lysosomes
35
self digestion if cell ruptures
autophagy
36
abundant in phagocytes
Lysosomes
37
vesicles formed by endocytosis fuse with lysosome to break down materials
Lysosome Action
38
small membranous vesicles containing enzymes that break down fatty acids, amino acids, hydrogen peroxide (H2O2) and other free radicals
Peroxisomes
39
reproduce by pinching in half but most bud off to the ER
Peroxisomes
40
is a byproduct of fatty acids and amino acid breakdown and can be toxic to a cell & is broken down into water or used in other reactions
hydrogen peroxide
41
responsible for producing ATP by aerobic metabolism. It has outer and inner membrane
Mitochondria
42
inner membrane of mitochondria forms ________, which is a gel-like substance that protrude into the matrix
cristae
43
Mitochondria doesn't reporduce with the cell — produces its own energy via _____________
endosymbiosis
44
used to be free living organisms ; thought to be eaten by bigger cells
Mitochondria
45
skeleton of all cells and consists of protein structures that support the cell, holds organelles, and enables cell to change shape
Cytoskeleton
46
What are the 3 cytoskeletal elements?
microtubules, microfilaments and intermediate filaments
47
smallest kind of site for cells, has two subunits --- globular actin and filamentous actin --- and is able to shorten or contract
Microfilaments
48
bigger than microfilaments; smaller than microtubules and the mechanical support
Intermediate filaments
49
hollow structure from protein subunits: alpha and beta tubulin. It help support cytoplasm, assist in cell division, form essential components like flagella and cilia
Microtubules
50
support cytoplasm and determine cell shape
globular actin and filamentous actin
51
where formation of microtubules occurs
Centrosome
52
2 centrioles are _____________ to each other
perpendicular
53
contain microtubule triplets and is involved in mitosis
centriole
54
cellular project of surface of cells and is responsible for movement of materials on top of cells
Cilia
55
cylindrical structures that extend from the cell and is composed of microtubules
Cilia
56
structure similar to cilia but much longer
Flagella
57
usually only occur once per cell
Flagella
58
supported by microfilaments and don't actively move
Microvilli
59
supported by microfilaments and don't actively move
Microvilli
