Bcannot synthesise; must get from diet

Dcan recycle indefinitely from old protein
Answer & Solution
Correct answer: B. cannot synthesise; must get from diet
An amino acid is 'essential' when the body cannot synthesise it from scratch
so it must come from food (typically 9 of the 20 in adult humans).
Frequency of use, charge, and recycling are not the definition.
