ATP: Adenosine Triphosphate

Mr. Anderson explains ATP, the energy currency of life, detailing its structure, formation, and role in energy storage and release. He covers ATP production in cellular respiration and photosynthesis, and its usage in active transport, muscle contraction, and polymer formation. The video also highlights ATP's evolutionary significance, being used by the Last Universal Common Ancestor and its presence in RNA and DNA.
