What organelle synthesizes hemoglobin of mammals?

The ribosome is the organelle that synthesizes hemoglobin in mammals. Ribosomes are small organelles found in all living cells and are responsible for protein synthesis. In mammals, hemoglobin is a protein molecule found in red blood cells and is responsible for carrying oxygen throughout the body. Ribosomes read the genetic information encoded in messenger RNA (mRNA) and use this information to assemble amino acids into a specific sequence, forming the hemoglobin protein.
