A specific protein that recognizes certain molecules bringing them across the membrane?

The protein you are referring to is likely a transporter protein, which is responsible for facilitating the transport of specific molecules across the cell membrane. These transporter proteins bind to their target molecules on one side of the membrane and undergo a conformational change to transport the molecules to the other side. Examples include glucose transporters and ion channels.


In what type of passive transport do protein channels assist molecules across the membrane?

In facilitated diffusion, protein channels assist molecules in crossing the cell membrane. This type of passive transport allows substances, such as ions and polar molecules, to move down their concentration gradient without using energy. The protein channels provide a pathway through the lipid bilayer, enabling the selective transport of specific molecules.


Through what type of proteins does active transport occur?

Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.


What type of organic molecule is needed for active transport?

ATP (adenosine triphosphate) is the organic molecule needed for active transport. It provides the energy required to pump molecules against their concentration gradient across a cell membrane.


The membrane-bound protein molecules that pass electrons along the Electron Transport System chain are called?

One major class are known as the Cytochromes.

What molecules would easily be able to diffuse through a cell membrane without the help of a transport protein?

Small, nonpolar molecules like oxygen, carbon dioxide, and water can easily diffuse through the cell membrane without the need for a transport protein. Their small size and lipophilic nature allow them to pass through the lipid bilayer of the membrane via simple diffusion.


What are the protein molecules in a cell membrane that assist in cell transport?

Protein molecules are responsible for membrane transport. In passive transport diffusion is the phenomenon in which molecules flow naturally from areas of high concentration to lower concentrations.

Are proteins necessary to transport oxygen to body?

A protein (hemoglobin) is required to transport Oxygen around the body.

ATP (adenosine triphosphate) is the organic molecule needed for active transport. It provides the energy required to pump molecules against their concentration gradient across a cell membrane.


Why the osmosis involves the movement of molecules via special transport protein?

facilitated diffusion


What protein recognizes certain molecules bringing them across a membrane?

channel or transport or receptor


Why do oxygen molecules easily diffuse across a cell membrane while protein molecules do not?

Oxygen molecules are small and non-polar, allowing them to easily pass through the phospholipid bilayer of the cell membrane via simple diffusion. In contrast, protein molecules are typically larger and may require specific transport proteins or channels in the membrane for facilitated diffusion or active transport to cross the membrane.
