Draw and explain the steps required for a cell to make and secrete adrenaline, starting with translation of adrenaline Please be precise, and trace the pathway of adrenaline through organelles from the time of its synthesis to its secretion into the blood stream. 13.(2.5 pts) Match the organelles with the correct function: Chloroplasts Golgi Lysosomes Mitochondria Phagosomes a.

Answer 1

Answer-

Adrenaline is catecholamine which is synthesized from the aminoacid tyrosine in the chromaffin cells of adrenal medulla. These hormones are formed from phenylalanine also. But phenylalanine has to be converted into tyrosine. The synthesis of protein adrenaline from aminoacid tyrosine is done by various processes, which is described below:
