Verified step by step guidance1
Understand the concept of energy currency in cells: Cells require energy to perform various functions, and this energy is often stored and transferred using specific molecules.
Identify the molecule that acts as the primary energy currency: In biological systems, the molecule that is most commonly used to store and transfer energy is adenosine triphosphate (ATP).
Learn the structure of ATP: ATP consists of an adenosine molecule bonded to three phosphate groups. The bonds between these phosphate groups store potential energy.
Explore how ATP releases energy: When ATP is hydrolyzed, it loses one phosphate group to become adenosine diphosphate (ADP), releasing energy that can be used by the cell.
Compare ATP with other molecules: While DNA and RNA are nucleic acids involved in genetic information storage and transfer, and NADH is involved in electron transport, ATP is specifically used as the energy currency in cells.
