What is forced transport?

Forced transport refers to the movement of substances across cell membranes against their concentration gradient, typically requiring energy input in the form of ATP. This process is essential for maintaining cellular homeostasis and involves mechanisms like active transport and bulk transport. Examples include the sodium-potassium pump and the uptake of glucose in intestinal cells. In contrast to passive transport, which relies on concentration gradients, forced transport actively regulates the internal environment of cells.
