Question

a pediatrician determines that a child has dangerously low levels of essential amino acids. as a result, this child may be (or may become) very ill, because the child’s cells need these amino acids to (directly) synthesize new:
○ proteins.
○ glycogen.
○ nuclei.
○ dna.

Explanation:

Essential amino acids are the building blocks directly used by cells to synthesize proteins. Glycogen is a carbohydrate (made of glucose), nuclei are cell organelles (not synthesized from amino acids), and DNA is a nucleic acid (made of nucleotides). Thus, the only molecule directly synthesized from amino acids is proteins.

Answer:

proteins.
