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.
The 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.

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
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.
the molecules are moving down their concentration gradient BACK NEXT
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

no. High concentration to low concentration. The molecules move down the concentration gradient.

Down the concentration gradient
The concentration gradient is what causes molecules to diffuse.

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
Molecules move a from regions where they are in higher concentrations to regions where they are in lower concentrations. Random
