3. Cellular Transport Flashcards
Movt of mol from low to high conc gradient that USES ATP
Active Transport
Types of Passive Transport
Simple
Facilitated
Osmosis
Simple diffusion is aka
Passive diffusion
Movt of solutes from Higher conc to Lower conc
Simple diffusion
Reason why gas exchange happens
Simple diffusion
Site of gas exchange
Alveoli
Facilitated diffusion is aka
Carrier mediated diffusion
A type of passive transport which needs carrier proteins
Facilitated diffusion
Insulin carrying glucose to insulin sensitive cells is what type of passive transport
Facilitated diffusion
3 insulin sensitive cells
Liver
Skeletal muscles
Adipocytes
Movt of water across a semi perm memb from LOW to HIGH osmotic pressure
Osmosis
It is det by the SOLUTES dissolved in the soln
Osmotic pressure
More solutes = __ Osmotic pressure
HIGH OP
Less solutes = ___ Osmotic pressure
Low OP
High conc of solute
Hypertonic
Low conc of solutes
Hypotonic
Soln has same solute conc of body cells
Isotonic
Cells in hypertonic soln results to
Shrinkage
Cells on hypotonic soln results in
Bursting
Used in surgery to irrigate tissues
Nss 0.9% NaCl
NSS or 0.9% NaCl is used to irrigate tissues during surgery because
It is isotonic, cells wont burst or shrink
4 example of Active transport
NaK pump
Proton pump
Exocytosis
Endocytosis
An example of an active transport that is used by the stomach to maintain its acidity
Proton pump
Acidic pH of stomach
ph = 1-3
