WebAmino acids enter cells from the blood principally by Na + -dependent cotransporters and, to a lesser extent, by facilitated transporters. The Na + -dependent transport in liver, muscle, and other tissues allows these cells to concentrate amino acids from blood. WebAs us have just seen, cells requesting a uniform supply of energy to generate and maintain the biological order that keeps them alive. This energy is from free the chemical bonded energy in food molecules, which thereby serve as fuel for cell. An officer website of the United States government.
