2 different ion or molecule in the same direction
What else can I help you with?
What is the difference between a symporter and an antiporter in terms of their mechanisms of transport across cell membranes?
A symporter moves two different molecules in the same direction across a cell membrane, while an antiporter moves two different molecules in opposite directions.
What is the difference between an antiporter and a symporter in terms of their mechanisms of transport?
An antiporter moves two different molecules in opposite directions across a cell membrane, while a symporter moves two different molecules in the same direction.
Movement of glucose across cell membrane of intestine?
Glucose can move via two ways: 1. With the Sodium/glucose pump. As sodium is diffusing back into the cell the glucose will attach itself (co-transport) as a symporter across the membrane. The sodium is going with the gradient and the glucose is moving against its gradient. Therefore, Indirect active transport via a symporter as a co-transporter. 2. By facillitated diffusion by attaching itself to a proten carrier glucose will move with the gradient into the cell. This means that glucose it the only molecule that can enter or leave a cell under two different transportation modes.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Does passive transport require ATP for the movement of molecules across the cell membrane?
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
Does facilitated transport require energy for the movement of molecules across the cell membrane?
Yes, facilitated transport does require energy for the movement of molecules across the cell membrane.
How does the cell transport materials across the cell membrane?
a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
What is the transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What is the glucose hitching a ride with?
Glucose hitches a ride with sodium through a symporter protein on the cell membrane. This process is known as secondary active transport, where the energy stored in the sodium gradient is used to transport glucose into the cell against its concentration gradient.
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
What are the types of membrane transport across the cell membrane require a protein carrier?
The brain
