#1
Front (Question)

Key properties of cell membranes

Back (Answer)

Semi-permeable Selective

#2
Front (Question)

Osmolarity

Back (Answer)

Solute concentration

#3
Front (Question)

Hypertonic

Back (Answer)

High solute concentration Gain water (THE SOLUTION)

#4
Front (Question)

Hypotonic

Back (Answer)

Low solute concentration Loses water (solution LOSES water into the cell)

#5
Front (Question)

Isotonic

Back (Answer)

Same solute concentration NO NET FLOW

#6
Front (Question)

Active Transport

Back (Answer)

Uses ATP

#7
Front (Question)

The fluidity of plasma membrane allows it to…

Back (Answer)

break and reform aroujd certain materials

#8
Front (Question)

Exocytosis

Back (Answer)

Materials released FROM a cell via vesicles

#9
Front (Question)

Endocytosis

Back (Answer)

Materials internalized within a vesicle

#10
Front (Question)

Intercellular vesicles….

Back (Answer)

move materials between cell organelles

#11
Front (Question)

Osmosis

Back (Answer)

The net movement of water molecules across a semi-permeable membrane

#12
Front (Question)

Simple diffusion

Back (Answer)

Small. Non polar

#13
Front (Question)

Examples of small or nonpolar molecules

Back (Answer)

H20 Glycerol

#14
Front (Question)

Examples of large polar molecules

Back (Answer)

Glucose Sucrose Potassium Sodium

#15
Front (Question)

Facilitated diffusion helps

Back (Answer)

Large, Polar, (ions and macromolecules)

#16
Front (Question)

Vesicle transport

Back (Answer)

ER to Golgi to Membrane

#17
Front (Question)

Step 1 of vesicle transport

Back (Answer)

A polypeptide is destined to be secreted Signal recognition polypeptides signal ribosome to rough ER

#18
Front (Question)

Step 2 of vesicle transport

Back (Answer)

Ribosome synthesizes polypetide in the lumen of rough ER

#19
Front (Question)

Step 3 of vesicle transport

Back (Answer)

Polypetide is transferred to golgi via vesicles budding from rough ER

#20
Front (Question)

Step 4 of vesicle transport

Back (Answer)

Polypeptide travles from cis to trans face of golgi via vesicles May be modified

#21
Front (Question)

Step 5 of membrane transport. FINAL

Back (Answer)

Polypetide is finally transferee to plasma membrane via vesicle where it’s secreted

#22
Front (Question)

Endocytosis is also

Back (Answer)

PHAGOCYTOSIS

#23
Front (Question)

Endocytocis does what

Back (Answer)

Engulfs material into an envelope. does not directly pass membrane

#24
Front (Question)

Exocytosis does what

Back (Answer)

Releases large substances via vesicles Does not travel across the plasma membrane
