Condensation What amino acid is classified as conditionally essential when dietary intake of phenylalanine is insufficient or the body cannot normally metabolize phenylalanine? a. Cysteine b. Tyrosine c. Glutamine 21.Explanation / Answer
15 a Pepsin
Pepsin is formed from pepsinogen for which HCl is required. Hence in the absence of HCl pepsin is not formed from pepsinogen
16) a Stomach.
Pepsin's digestive power is highest at the acidity levels of ordinary gastric juice. It s inactive at intestinal pH
17 c denaturation
This process involves the disruption or destruction of both the secondary and tertiary structures but not the primary stucture of a protein.for example heating of egg albumin causes change in the structure. Denaturation is a irreversible process
18 c The hemoglobin molecule is made up of four polypeptide chains ie two alpha chains and two beta chains
