Aspartate + a- keto acid >> Oxaloacetate + a amino acid
This reaction is occur because the a- keto acid in the equation can come from any amino acid, the 15 N from aspartate is rapidly transferred to other amino acids.
15N is symbol use as the isotope of nitrogen with mass number 15. comprises of 0.4 % of stable nitrogen found, so the relative abundance of each in amino acid is simply a reflection of how much is found in nature in general.
This isotopes is enrichment of the labelled amino acids was determined following a previously developed procedure comprising by determination of the spectral purity of the selected natural abundance amino acids.

400x because you have to multiply that 40 by that 10
Answer:
Intracellular receptors are located within a cell and bind to molecules that cross directly through the membrane. Membrane receptors are located in the membrane, bind to molecules that cannot cross it, and transmit the signal to the cell interior by changing shape.
