Question

q20: define complete and incomplete protein.
complete protein:
incomplete protein:
q21: define fat-soluble and water-soluble vitamins.
fat-soluble:
water-soluble:

Explanation:

A complete protein contains all nine essential amino acids in sufficient amounts for the body's needs. An incomplete protein lacks one or more essential amino acids. Fat - soluble vitamins (A, D, E, K) dissolve in fat, are stored in the body's fatty tissues, and can accumulate to toxic levels. Water - soluble vitamins (B - complex and C) dissolve in water, are not stored in large amounts, and are excreted in urine if in excess.

Answer:

Complete Protein: Contains all nine essential amino acids. Incomplete Protein: Lacks one or more essential amino acids. Fat - soluble: Dissolve in fat, stored in fatty tissues, can accumulate. Water - soluble: Dissolve in water, not stored in large amounts, excreted.
