These organelles grow by the incorporation of proteins and lipids, a process that occurs continuously during the interphase period of the cell cycle. ... Most chloroplast and mitochondrial proteins, however, are synthesized outside the organelle on cytosolic ribosomes that are not bound to the rough endoplasmic reticulum.

Explanation:
In stomach- Digestion of protein starts in stomach with the help of enzyme pepsin. Pepsin is secreted in inactive form pepsinogen by the chief cells present in stomach. Hydrochloric acid secreted by parietal cell in stomach activates pepsinogen into pepsin.
Pepsin then hydrolysed the protein molecules and converts them into proteoses, peptones and larger peptides.
Then the food moves into small intestine where protein digestion remains continued.
In small intestine, pancreatic juice contains inactive proteases named as chymotrypsinogen, trypsinogen and procarboxypeptidase.
