Cellular Organelles Flashcards
1
Q
cell membrane
structure
A
- lipid bilayer
- protein
- cholesterol
2
Q
lipid bilayer
function
A
separate out from in
3
Q
cell membrane - protein
function
A
integral: pore (allow H20 soluble through)
peripheral: spectrin
4
Q
cell membrane
function
A
separate cell from environment; control movement of substances across membrane
5
Q
nucleus
structure
A
outer membrane continuous with ER
6
Q
nucleus
function
A
site of DNA replication and transcription of DNA->RNA
7
Q
Endoplasmic reticulum
structure
A
Rough ER
Smooth ER
8
Q
Endoplasmic reticulum
function
A
- membrane and secreted protein synthesis
- membrane phospholipids and cholesterol synthesis
9
Q
Golgi apparatus
structure
A
5 stacks (cis next to ER; trans toward membrane)
10
Q
golgi apparatus
function
A
- addition and removal of sugars (glycosylation)
- synthesis of glycocalyx
11
Q
Glycocalyx
structure
A
negatively charged glycolipids/proteins
12
Q
glycocalyx
function
A
- only on outside of cell
- ABO blood type, immune & autoimmune function
13
Q
Lysosome
structure
A
vesicle filled with digestive enzymes
14
Q
lysosome
function
A
- enzymes=acid hydrolases
- protease breaks down protein
- lipase breaks down fats
- amylase breaks down carbs)
15
Q
mitochondria
structure
A
outer and inner membrane with matrix
