Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Ok, no more fun stories. Here’s a definition:the movement of molecules across the cell membrane from LOW to HIGH concentration. But wait there’s more!!!!! It needs energy to do this!!

A	Passive Transport
B	Diffusion
C	Osmosis
D	Active Transport

Explanation:

Detailed explanation-1: -Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, going from a low concentration to a high concentration.

Detailed explanation-2: -Answer and Explanation: The movement of molecules across a membrane requiring energy to be expended by the cell is called active transport.

Detailed explanation-3: -“Passive transport is the movement of ions and molecules across the cell membrane without requiring energy.”

Detailed explanation-4: -Sometimes, molecules cannot move through the cell membrane on their own. These molecules need special transport proteins to help them move across the membrane, a process known as facilitative diffusion. These special proteins are called channel proteins or carrier proteins.
