- 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
- by the removal of 1 phosphate group at a time; during the reaction of hydrolysis
- 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
