The cell is equipped with a special system to prevent amino
acid starvation. These control systems work as follows: tRNA
molecule in the cell is responsible for the transportation of
amino acids to the ribosome, which can be called the protein

production factory of the cell. GCN2 molecule binds to free tR-
NAs, which means that GCN2s will bind to tRNAs when amino
acid levels drop. This way, they activate elF2 alpha molecule,
which has two opposing tasks. When the amino acid levels go
down in the cell, the protein production system will be sup-
pressed. This is a designed decision because when there is a
shortage of amino acids, ribosome must not consume the al-
ready limited sources. However, the system will increase the
production of certain amino acids must also be put into motion.

Very surprisingly, elF2 alpha, after stopping the general protein
production, increases the production of proteins in charge of
increasing the amount of amino acids. 123-124
This entire control, inspection of the levels of substances in
the cell, intelligently stopping various production systems while
increasing others, requires foresight and detailed knowledge.
