A transport protein that simultaneously transports two different molecules in different directions is called:
A
A uniporter
B
A symporter
C
An equilibrium protein
D
An antiporter
E
A simple diffuser
Verified step by step guidance1
Understand the concept of transport proteins: Transport proteins are integral membrane proteins that facilitate the movement of molecules across the cell membrane.
Differentiate between types of transport proteins: Uniporters transport a single type of molecule across the membrane, symporters transport two different molecules in the same direction, and antiporters transport two different molecules in opposite directions.
Identify the function of an antiporter: An antiporter is a type of transport protein that moves two different molecules in opposite directions across the membrane.
Consider the given options: Evaluate each option based on the definitions of uniporter, symporter, and antiporter.
Select the correct answer: Based on the definition, the transport protein that simultaneously transports two different molecules in different directions is an antiporter.
