Plama / Cell Membrane

Question 1

Phospholipid bi layer

Answer 1

Polar head/ non polar tails of phospholipid molecules. And bimolecular lipid layer.

Question 2

Peripheral protein

Answer 2

Enzyme. Amphipathic. Outside or inside cell

Question 3

Integral proteins

Answer 3

Travels all the way or half way through lipid bi layer. Used to transport protein

Question 4

Answer 4

Cell receptor/ cell recognition.

Carb c protein

Question 5

Glycolipid

Answer 5

Cell receptor/ cell recognition.

Carb c lipid

Question 6

Cholesterol

Answer 6

Stabilizes cell membrane.

Question 7

Cytoplasm

Answer 7

Cellular region between nuclear and plasma membrane. Consist of cytosol (liquid) and organelles

Question 8

Mitochondria

Answer 8

Site of ATP synthesis. Power house of cell. (Can replicate)

Question 9

Ribosomes

Answer 9

Site of protein synthesis. (Doesn’t have membrane)

Question 10

Rough endoplasmic reticulum

Answer 10

Makes a lot of proteins that are secreted from cell. Makes cell membrane

Question 11

Smooth endoplasmic reticulum

Answer 11

Makes lipids. Site of lipid and steroid synthesis. Lipid metabolism and drug detox

Question 12

Golgi apparatus

Answer 12

Modifies/segregates protein (final product) for secretion

Question 13

Lysosomes

Answer 13

Intercellular digestion. (Breaks things down/ can be reused)

Question 14

Centnoles

Answer 14

Forms spindle and asters in mitosis. Doesn’t have membrane

Question 15

Nucleus

Answer 15

Control center of cell. Responsible for genetic info and providing instructions on protein synthesis

Question 16

Nuclear envelop

Answer 16

Regulates passage of substance to and from nucleus. Separates nucleoplasm from cytoplasm

Question 17

Nucleoli

Answer 17

Where ribosomes are made

Question 18

Chromatin

Answer 18

DNA constitutes gene

Question 19

Plasma membrane

Answer 19

External cell barrier.

Consist of Phospholipid bi layer, Peripheral proteins, Integral proteins, Glycoproteins, Glycolipids, Cholesterol.
