Which amino acids are the primary nitrogen donors for biosynthetic reactions in the cell?

Question

Quizplus · Accepted Answer

Glutamine and glutamate are the primary nitrogen donors for biosynthetic reactions in the cell, as they are involved in the transfer of amino groups to other molecules. Glycine and serine do not transfer amino groups in biosynthetic reactions, and while glutamate does play a role, it is primarily the precursor for glutamine synthesis. Serine is not involved in nitrogen donation in biosynthesis.
