    A few ions or molecules are transported across the membrane against their concentration gradient, i.e., from lower to higher concentration. Such type of transport is called active transport because it is an energy-dependent process in which ATP is utilised, e.g., Na+/K+ pump. https://youtu.be/visqfZd7Ms4 Active transport uses energy to pump molecules against a concentration gradient. Active…
