The transport protein allows substances to travel across the cell membrane. The substance is traveling from low concentration to a higher concentration. The process requires energy and is called active transport. The protein is simply called a transport protein.

∙ 15y agoThe carrier protein that pumps sodium ions out of a cell, and potassium ions into the cell, is often called the sodium-potassium pump.

Another carrier protein carries sodium, potassium, and chloride ions all in the same direction; that is the Na-K-Cl cotransporter.

How does endocytosis differ from the process shown in transparency?
Endocytosis is a process which allows a cell to engulf molecules in their entirety and surround those molecules in a membrane. Transport is when small molecules can actively transport through a cellular membrane and come out again.
What transport protein allows ions to pass through the cell membrane?
Ion Channels allows ions to pass through the cell membrane.
What are different types of tranport mechanisms?
There are two main types of transport systems which are used to transport solutes across a cell membrane: passive transport and active transport. Passive transport is where a protein in the membrane simply provides a 'hole' in the membrane, which allows the solute to flow freely in both directions. In this case, the flow of the solute is determined entirely by the concentration gradient across the membrane, and no energy is input to aid the movement (hence the term passive). Active transport is where the protein in the membrane actually binds to the solute, and conformational changes in the protein shape literally carry the solute across the membrane, then release it on the other side. This mechanism is designed for situations where movement of solutes against their concentration gradient is required, and requires the input of energy. This energy can come from one of a few places: * Primary active transport involves deriving the energy required to move the solute from the hydrolysis of ATP (Adenosine Triphosphate). In this case, the protein acting as the carrier is referred to as an ATPAse. * Secondary active transport involves deriving the energy from the movement of another solute across the membrane. This second solute will be flowing in the direction of its concentration gradient, so energy is released as it crosses the membrane. This allows it to drive the conformational changes in the protein that carry the solute across.
What is the protein that allows facilitated diffusion of water?
In the facilitated diffusion the transport protein is needed as well in the active transport.
Does active transport involve phosphoralization?
Yes primary active transport machinery (protein pumps) relies on phosphorylation of the carrier protein. ATP hydrolysis yields the phosphate molecule to interact with the protein pump. This cause the conformational change in the ion channel protein to carry out exchange of ions. For example: sodium-potassium pump: binding of phosphate release sodium from cell, whereas dephosphorylation allows the entry of potassium ions inside the cell.
What is the name of the protein found in erythrocytes that allows for respiratory gas transport?

Which part allows or prevents substances to go into and out of the cell?
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
What is the protein that allows facilitated diffusion of water?
In the facilitated diffusion the transport protein is needed as well in the active transport.
Which process allows ions to move across a semipermeable membrane where the concentration of ions is low to where their concentration is even higher?
Active transport BIOLOGY APEX

The shape of a protein allows it to perform its particular job.
Which process is responsible for moving cellular wastes across the cell membrane?
The process for moving cellular wastes across the cell membrane is known as active transport. Active transport is a source of energy that allows molecules to move from low concentrations to high concentrations, and provides the needed boost to move the molecules uphill.
