Homework Answers

Answer #1

There are 2 types of active transport :

1) Primary Active transport - Energy derived by itself to transport ion

E.g. Na+K+ATPase pump

2) Secondary actve transport -- Energy derived from transport of some other ion

a)Co-transport - Transport in the direction of primary ion flow.

E.g. NaGlucose Symport.(SGLT)

Na Phosphate Co-transport ( NaPi IIa/b)

Na Iodide Symporter (NIS)

Na+/K+/Cl- Co-transporter

K+/Cl- Co-transporter

b) counter tranport - transport indirection opposite to direction of primary ion flow

E.g. Na+Ca2+ antiport

c) Uniport
