Transporter protein that carries a substance across a cellular membrane against its concentration gradient?
pump
A transporter protein that carries a substance across a cellular membrane against its concentration gradient?
pump
What is A transporter protein that carries a substance across a cellular membrane against its concentration gradient?
pump
What are the special structures in the membrane that allow materials as water and sugar to pass through made of?
Membrane transporter.
A transporter protien that carries a substance across a cellular membrane against its concentration gradient?
Sodium potassium ATPase pump.
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
The net flow of materials through the membrane of a cell against a concentration gradient is?
It's Active Transport.
How does the na-k atpase pump works?
3 Na+ ions attach to the transporter. ATP hydrolyzes, releasing a phosphate which binds to the transporter, causing a conformational change that releases the Na+ ions and phosphate to the cytosol. The decrease in Na+ ions causes an electrochemical gradient in the cell which attracts the K+ ions to the transporter which are brought in passively due to the electrochemical gradient. This maintains the membrane potential and osmotic pressure of the cell.
Which transport mechanisms moves materials across a plasma membrane against an apparent concentration gradient?
active transport
What is the process in which particles move through a membrane from a region oflow concertration to a region of high concertration?
This process is known as diffusion. Under circumstances of a permeable membrane, solutes will always flow from areas of higher concentrations to lower concentrations until an equilibrium is established
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is used to move molecules and ions across a membrane against their concentration gradient. "Active" means that the transporter requires energy to do its job (eg. glucose).
What are the special structures in the cell membrane that allow materials such as water and sugar through made of?
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
