Membran Transport 2 Flashcards
Types of active transport
Primary
Secondary
Endocytosis
Exocytosis
Difference between primary & secondary
Primary uses direct ATP while secondary uses indirect from primary
What differentiates active from passive
Need ATP, carriers, against concentration electro chemical gradient.
Examples of primary transport
Na+ k+ pump
Ca+ pump
H+ pump
Calcium pump
In the cell ca2+ out
Into mitochondria
In muscles sarcoplasmic reticulum(inside)
H+ pump
Parietal cells & inter calated cells
Types of 2ndry transport
Co-transport & counter transport (symport, antiport)
Co transport ex?
Sodium- glucose
Sodium - amino acid
Counter transport ex?
Sodium -calcium
Sodium- hydrogen
Pinocytosis - phase cytosine
ECF _ No ECF canbe digestedif digestible by lysosome
