Question

where or how are essential amino acids obtained?
by making them from other amino acids
from carbohydrates in the diet
from oils and fats in the diet
from proteins in the diet
from fruits and vegetables

Explanation:

Essential amino acids cannot be synthesized by the human body and must be obtained from dietary sources. Proteins are composed of amino acids, so consuming dietary proteins (from animal or plant sources) provides these essential amino acids. Other options like carbohydrates, fats, or fruits/vegetables do not directly supply essential amino acids; the latter may contain some but are not the primary source, while the correct primary source is dietary proteins.

Answer:

from proteins in the diet
