the full form of ATPATP: Adenosine TriphosphateATP stands for Adenosine Triphosphate. It a high-energy molecule found in the cells of the human BODY, animals, plants, etc. It is capable of storing and supplying the energy needed by cells. So, it is COMMONLY known as the energy currency of the cell.The human body is made up of different types of cells. Each type of cells performs a specific function that helps organisms to perform TASKS necessary for survival. For example, nerve cells communicate messages to the brain and allow us to think, make decisions and more. Similarly, muscle cells help us to produce force and motion, maintain posture, and contraction of organs, and more. Cells need the energy to perform these tasks, which is provided by ATP.The food that we EAT is gradually oxidized in the cells and energy is released, which is used to produce the ATP so that a continuous supply of ATP is maintained. In simple words, we store the energy OBTAINED from the breakdown of food as ATP. Similarly, plants store energy produced during photosynthesis in ATP molecules.
