Understanding ATP: The Energy Currency of Life

Mr. Anderson explains ATP, the energy currency of life, detailing its structure, function, and role in cellular processes. ATP consists of adenine, ribose, and three phosphate groups, storing energy in its bonds. It is produced in cellular respiration and photosynthesis, and used in active transport, muscle contraction, and polymer formation. ATP's evolutionary significance is highlighted, showing its presence in all life forms and its role in early genetic material.
