What substances are transported by active transport?
Sodium Potassium
What is the process called when sodium NA is pumped out of a nerve cell?
during action potentials, sodium and potassium cross the membrane of the synapse after the threshold of membrane potential is reached. There, sodium leaves the synapse and the membrane potential is now positive. this is known as depolarization. then during repolarization, the sodium channels close and the potassium channels open to stabilize the membrane potential. during this time, a second action potential cannot occur and this is an evolutionary advantage because it allows rest in the nerve cells and it allows the membrane potential to equalize.
What cell gates open immediately after action potential peak?
Sodium and potassium voltage gated ion channels.
In active transport carrier proteins?
sodium-potassium pump.
What type of channel is responsible for action potential?
Remove this? Has been answered in similar question. Calcium, Potassium, Sodium.
The transport of food into cells involves the action of the sodium-potassium pump and channels?
coupled
What substances are transported by active transport?
Sodium Potassium
Does facilitated transport have a sodium potassium pump?
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.

What is the effect of decreasing the number of sodium potassium pumps?
When number of sodium-potassium pump decreased, transport of Na takes little more time. Less number of sodium-potassium more time for transport
What cell gates open immediately after action potential peak?
Sodium and potassium voltage gated ion channels.
An example of active transport?
sodium-potassium pump
Sodium potassium pump is an example of what?
Active transport
What protein that allows ions to actively transport across?
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.
What is the active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.?
sodium-potassium pump
In active transport carrier proteins?
sodium-potassium pump.
Is a sodium potassium pump active or passive transport and describe why.?
Potassium is distributed by passive diffusion.
