  • ATP
  • complex, organic molecules
  • stores + provides energy for life processes
  • provides chemical energy to drive chemical reactions for the cell
  • is the chemical energy that powers our characteristics of life
  • produced during cellular pathways that break down glucose
  • made from other chemical components
  • has nitrogenous base ; adenine', the sugar ribose + 3 phosphate groups
    • made of a phosphorous atom, surrounded by 4 Oxygens
  • stored in chemical bonds in its phosphate tail
  • using energy to reconnect a phosphate group means cells can make ATP from ADP
  • to release energy, ATP is broken down from the tip of the tail
    • by the removal of 1 phosphate group at a time; during the reaction of hydrolysis
      • produces a free phosphate group + ADP
  • energy in the bonds of glucose is transferred to the bonds in an ATP molecule
  • produced through several different cellular processes
  • first step of breaking down glucose required ATP
  • the breakdown produces more ATP energy than requires
    • ,all that ATP is used to drive activites of the cell + must be constantly produces
  • cell use ATP to move molecules, ions + other substances across the cell membranes
  • Sometime, energy may be needed to bring in or carry out substances for the cell, depending on its enviroment
    • known as 'active transport'
  • a break down in the ATP process, will kill a cell
  • powers muscles. processes of cellular respiration + glycolysis provide ATP for your muscles
  • used as a primary source of energy for the work
  • constantly produced in the muscles as they do their work
