What mechanism does a cell use to move small potassium molecules into the cell against the concentration gradient?

To transport any molecules against a concentration gradient, ATP is required. This process is called active transport. Active transport is enabled by carrier proteins which are located in the cell membrane.
To transport charged molecules through the membrane, pore proteins are required.

∙ 10y agoThe sodium potassiumn pump (Na+/K+ ATPase) is a membrane channel protein which maintains cells' membrane potential.
This enzyme is capable of ferrying 3 Na+ ions from the cell interior to the exterior, while simultaneously moving 2 K+ ions to the inside of the cell. In order to facilitate this exchange against the concentration gradients normally present around cells, one ATP is hydrolysed to ADP + Pi.

What does it mean when you are going with the concentration gradient?
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration
Why does active transport require more energy than osmosis or faciliated diffusion?
It is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
As the concentration of molecules outside a cell increases more molecules will enter the cell?
the molecules are moving down their concentration gradient BACK NEXT
During diffusion molecules tend to move?
AnswerParticles move from regions of higher concentration to regions of lower concentration because of the concentration gradient,they move down gradient i.e from high to low concentration
What condition exists when you have a high concentration of molecules in one place and a low concentration in an adjacent place?
Concentration Gradient
What mechanism does a cell use to move the small potassium molecules into the cell against the concentration gradient?

What is the active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.?
sodium-potassium pump
Do substances in diffussion move with the concentration gradient?
no. High concentration to low concentration. The molecules move down the concentration gradient.

Where do diffusion molecules move?
Down the concentration gradient
What determines how molecules are distributed in diffusion?
The concentration gradient is what causes molecules to diffuse.

What do molecules move along in diffusion?
Molecules move a from regions where they are in higher concentrations to regions where they are in lower concentrations. Random
