ATP

• Adenosine triphosphate (ATP)

  The energy currency of the cell that provides the energy for the vast majority of reactions that take place in living organisms
• ATP

  • Made up of three main components: the nitrogenous base adenine, the sugar ribose, and three bound phosphates
• ATP gives one of its phosphates and becomes ADP (adenosine diphosphate)

  1. The phosphate that it gives provides energy for a reaction

  2. The phosphate is then reattached in a separate reaction
• ATP

  A high energy compound that gives off some of its energy and becomes ADP, a low energy compound
• Source of energy for ATP

  The Sun is the main and major source of energy for all living things
• Plant cells produce ATP

  1. Through light reactions in the chloroplast during photosynthesis

  2. They then use that ATP to produce sugars like glucose
• Animal cells form ATP

  1. By breaking down glucose in glycolysis and cellular respiration

  2. Most of this takes place in the mitochondria
• The energy your body uses every day literally came from the Sun
• ATP is the energy currency of the cell
• ATP is produced in animal cells by breaking down glucose
• The energy in ATP ultimately comes from the Sun
