Movement and accumulation of ions across a membrane against their concentration gradient can be explained by
Active transport uses energy to move substances against the concentration gradient.
Active transport is a type of cellular transport in which substances like ions, glucose and amino acids are transported across a biological membrane towards the region that already contains a lot of such substances. In active transport, chemical energy (e.g. ATP) is used to transport such substances against the concentration gradient.
