basic terms and cell stuff Flashcards
Osmosis depends on
- solute concentration difference
* membrane must be impermeable to the solute
What do transport proteins do (SSAAI)
They cross sugars, salts, amino acids, Ions
The phospholipid bilayer allows for
- small uncharged non polar molecules
- Gasses
- Simple diffusion
glosso
tongue
Rates of diffusion depend on
- difference in concentration
* Permeability

Phospholipid bilayer and transport proteins are located in
Plasma membrane
anterior/ posterior
front / back
transverse dissection
top and bottom
Primary Active transport
ATP is directly responsible for Transport Protein Fuction
Na+/k+ pump
3 sodium out of cell and 2 potassium into the cell
Solute
dissolved molecules
Second messengers
cAMP
IP3
medial/lateral
middle/side
Cereb
Brain
Meso
middle
what is the coronal/ frontal plane
it give a front and back dissection
Sub
under
Secondary Active transport
Moves sugars and amino acids
Channels
facilitated diffusion
Exocytosis
large molecules out (enzymes, hormones, neurotransmitters)
The Ca2+ pump
helps release neurotransmitter in neurons and muscle contractions
Osmosis
Water travels to and from the plasma slowly
hyper

sagittal plane dissection
right and left
Hypertonic Solution
Solute concentration inside the cell is lower than the fluid surrounding it
Heemi
Half
endo
within
cranial/ caudal
Head/ tail
afferent/efferent
going into/ exiting
Simple and facilitated diffusion
movement from high to low concentration
Cell signaling Short distance
- gap junctions-between the cells
* paracrine signaling- cells near organs secrete molecules (local signaling)
Solution
Solvent and water
Epi

Osmosis movement
Low solute to high solute concentration
Hypotonic Solution
Solute concentration inside the cell is higher than the fluid surround it
superior/ inferior
above/ below
Pumps
active transport (ATP)
Cell signaling Long distance
- Synaptic signaling - neurons secreting neurotransmitters
* Endocrine signaling- Glands that secrete hormones
Iso
