Study Notes
ATP: The Cell's Energy Currency
- ATP (adenosine triphosphate) is the primary energy source for most cellular activities.
- It provides energy for synthesis of macromolecules, such as proteins, carbohydrates, and nucleic acids.
- ATP powers muscle contraction, enabling movement and mechanical work.
- It fuels active transport across cell membranes, allowing cells to regulate the movement of molecules.
- ATP is essential for cell division, enabling the duplication of genetic material and the separation of daughter cells.
Discover the crucial function of ATP in powering cellular processes, from synthesis of macromolecules to muscle contraction and cell division. Learn how ATP serves as the primary energy source for cells. Get ready to energize your knowledge!
