Question

Difference with primary and secondary active transport

Answer 1

Answer:

Primary active transport utilizes energy in form of ATP to transport molecules across a membrane against their concentration gradient. Therefore, all groups of ATP-powered pumps contain one or more binding sites for ATP, which are always present on the cytosolic face of the membrane.

Based on the transport mechanism as well as genetic and structural homology, there are considered four classes of ATP-dependent ion pumps:
