The cells need to get glucose, amino acid, and oxygen from outside the body in order to function properly.

  • Cells need to obtain oxygen and glucose to carry out cellular respiration.

  • Cellular respiration is a fundamental cellular process by which cells produce ATP, the energy coin of the cell.

  • Moreover, amino acids are fundamental building blocks for cells in order to synthesize proteins.

  • Essential amino acids cannot be synthesized by the human body.

  • The essential amino acids include isoleucine, leucine, histidine, lysine, phenylalanine, threonine, methionine, tryptophan, and valine.

In conclusion, the cells need to get glucose, amino acid, and oxygen from outside the body in order to function properly.
