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…

Electron Transport Chain: The Powerhouse of Cellular Respiration
Introduction: Structure of the Electron Transport Chain Complexes of ETC: The ETC is made up of four protein complexes: Complex I, Complex II, Complex III, and Complex IV. Each complex has a specific function in the ETC, and the electron transfer between complexes is tightly regulated. Complex I (NADH-CoQ oxidoreductase): Complex I is the first…
