BULK TRPT is endo or exo = |
Endocytosis = 3 types =
|
Fluid phase pinocytosis:
Receptor mediated endocytosis: Phagocytosis: |
|
|
Fluid phase pinocytosis: uses a =
|
Pinocytotic vesicle
is it a Bulk Trpt = |
YES
|
|
|
Receptor mediated endocytosis: uses a =
|
coated vesicle
is it a Bulk Trpt = |
YES
|
|
|
Phagocytosis uses a =
|
phagosome
(scan for nonself) engulf & degrade by enzymatic process. is it a Bulk Trpt = |
YES
|
|
|
Pino means what in Gk
|
(Gr = drinking)
|
|
|
|
Exocytosis = Things going out
Has 2 pathways |
~Constitutive Secratory Pathway means what =
~Regulated Secretion Pathway ie = |
(Constitutive = means always)
(Insulin any stored proteins) |
|
|
Plasma Membrane Fctn =
2ct |
1) Selective barrier = describe
2) Communication = describe |
– semipermeable membrane: regulates cell content / volume
a. messages from outside of cell to inside (hormones, etc.) b. messages between cells (Gap Junctions) |
|
|
nfo: Membrane proteins are excellent targets for
|
Chemotherapeutic Rx

Signal Receptor 4ct =
A P E S |
Autocrine signal
Paracrine signal Endocrine signal Synaptic signal Describe each = |
a: Autocrine signaling: chemical mediators acts on the cell that produced it.
b: Paracrine signaling: chemical mediators secreted from one cell & acts on adjacent cells. c: Endocrine signaling: hormone discharged into blood and transported to effector cell. d: Synaptic signaling: neurotransmitter act only on adjacent nerve cells through synapse. |
|
|
a- Autocrine signal
describe = |
signals itself)
|
|
|
|
b- Paracrine signal
describe = |
(signals a neighbor or passer by…something close)
|
|
|
|
c- Endocrine Signal
describe = |
Hormone mediated …discharges hormone in heme...
Trpt to target effector |
|
|
|
d- Synaptic signal
describe = |
(neurotransmitter act only on adjacent nerve cells through synapse )
|
|
|
|
Signal Receptors for PM
2 classification = |
Hydrophobic Signaling =
Hydrophilic Signaling = |
Steroid / Hormone (They pass through the plasma membrane)
G Proteins because they bind to Guanine Nucleotides |
|
|
Ligand bind to receptor ---- >
|
change confirmation --- >
|
transcription Fctr --- >
change expression (or not depending on cell) |
|
|
Different steps in signaling can cause same =
