Membrane Potential
The membrane potential is a fundamental concept in cellular physiology, playing a crucial role in the proper functioning of cells. It refers to the electrical potential difference across a biological cell membrane, which is maintained by ion gradients. These gradients are created by the selective permeability of the membrane to ions such as sodium, potassium,…

Active Transport
Active transport is a fundamental process in cellular biology that enables the movement of molecules across cell membranes against their concentration gradient. It requires the expenditure of energy, typically derived from ATP. This article explores the different types of active transport, including primary and secondary active transport, as well as cotransport. It highlights the significance…
