In this instance, increases in pressure lead to an increase in the prevalence of collisional processes in the sheath, which in turn serve to bring about a broadening of the IEDFs and a … WebATP is an energy molecule, and when hydrolysis happens, it gets broken down to release the energy that was stored in its chemical bonds. Transport that directly uses ATP for energy is considered primary active transport. In this case, that’s moving sodium from a concentration of 10mM to one of 145 mM. is eleven the demogorgon
