The low status of smell in Western culture is reflected in our language: colloquial terms for ânoseâ, for example, are almost all derogatory, or at the very least disrespectful (schnozzle, conk, hooter, snoot, snout, etc.) â and large or distinctive noses are considered ugly.
Ribosomes are organelles composed of ribosomal proteins (riboproteins) and ribonucleic acids (ribonucleoproteins). The word ribosome is made from taking â ribo â from ribonucleic acid and adding it to â soma â, the latin word for body. Ribosomes are bound by a membrane but they are not membranous.
The endoplasmic reticulum is made up of membranous sacs and tubules. It has two different portions: the smooth endoplasmic reticulum and the rough endoplasmic reticulum. The rough endoplasmic reticulum is studded with ribosomes and produces proteins that are incorporated into cellular membranes outside of the cell. The smooth endoplasmic reticulum lacks ribosomes on its cytoplasmic surface.
