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…

Osmosis
Osmosis is a process that occurs naturally in all living things, including plants and animals. It is a type of passive transport that involves the movement of water molecules across a selectively permeable membrane from an area of high concentration to an area of low concentration. This movement of water molecules helps maintain the balance…
