Explain how a cell production of thyroxin would be effect if its lysosomes be not functioning.?
Answer:
Extracellularly occurring lysosomal enzymes are involved in the proteolytic release of thyroxine from thyroglobulin.
TSH induces the secretion of cathepsin B, which contributes to the extracellular release of thyroxine by thyrocytes.
Theoretically non functioning lysosomes inhibit thyroxine production.
