Which amino acids are synthesized from intermediates of Krebs cycle like alpha-ketoglutarate and oxaloacetate?
Options
- ALysine and aspartic acid
- BGlutamic acid and mevalonic acid
- CAspartic acid and mevalonic acid
- DGlutamic acid and aspartic acid
Correct answer
D. Glutamic acid and aspartic acid
Step-by-step solution
The intermediates of the Krebs cycle serve as precursors for the synthesis of various amino acids through transamination reactions. -ketoglutarate undergoes reductive amination or transamination to form glutamic acid (glutamate). Oxaloacetate undergoes transamination, accepting an amino group from glutamate, to form aspartic acid (aspartate). Therefore, glutamic acid and aspartic acid are the amino acids synthesized from -ketoglutarate and oxaloacetate, respectively. Answer: Glutamic acid and aspartic acid
